The 7 Step Journey to Network Resilience

Keeping i3D.NET Undefeated By Downtime

Opengear Solutions for Network Resilience

Ensuring network resilience is an important business priority for To maintain its global operation, runs a complex low-latency network, with thousands of servers spread over more than 35 points of presence on 6 continents.

It is key that this network is kept up and running at all times. As Rick Sloot, chief operations officer, explains: “Ten years ago, this was very difficult to achieve. There were very few ways of handling and managing your servers when the internet went down and those that were available were expensive and did not work well. As technology has advanced over the past decade, customer expectations have grown in line, and a high level of network resilience is now demanded by our users.”

“As we expanded as a business, opening up new locations around the world, it was becoming increasingly difficult to find a vendor capable of delivering a reliable way of keeping us up and running at all times, across all our locations.” continued Sloot.

“We struggled to find local vendors who could support us. Often, we weren’t able to pinpoint the issue or access the faulty equipment. We needed to find a way of managing equipment remotely, identifying and resolving the problem, while keeping the network online. “We started to look for a vendor who could work with cellular technologies such as 4G and who could deliver out-of-band management. Opengear fitted the bill perfectly. Opengear’s tools can support 4G cellular out-of-band connections in all our global locations which have enabled us to save time and money. We were looking for a partner that could deliver triple-A equipment on time all over the globe and knew we could rely on Opengear for this.” decided to work in partnership with Opengear and implement its ACM 7008-2-L Resilience Gateway to provide smart out-of-band management to its entire IT infrastructure, and also to provide a built-in backup LAN and/ or backup Internet connectivity option for all their remote sites.

Reaping the Rewards

Today, uses the Opengear Resilience Gateway as a fall-back, providing out-of-band management, as and when required, to its routers all over the world. It has achieved a raft of benefits as a result. For example, it has helped to significantly streamline the process of bringing new sites online.

In the past, when had to carry out a deployment outside the Netherlands, a technical operations engineer flew to the location and installed the new switches but would typically struggle to configure them. Today, simply connects the Opengear Resilience Gateways to these network switches and its network operations engineers back in the Netherlands are then able to configure the whole site remotely via the Opengear device. “This is very powerful and a huge benefit for us in terms of the time and costs saved not only in provisioning but also ongoing maintenance” commented Sloot.


“We were looking for a partner that could deliver triple-A equipment on time all over the globe and knew we could rely on Opengear for this.”


Using Opengear Resilience Gateways also allows to stay one step ahead of any pending network failures. According to Sloot: “We don’t like downtime and neither do our customers. Today, if there is an issue, we can directly connect to our routers anywhere in the world without having to wait for someone at the locations to access and fix it. The agility of the Opengear solutions means we can quickly help our customers and maintain our high standards as a performance hosting company.”

Looking Ahead

Today, continues to expand and open global locations dynamically. It is also in the process of switching to a new Juniper Networks router platform. As Sloot explains: “This will give us the opportunity to launch our Global Low-latency Anti-DDoS solution (GLAD). Every region where we are changing the router and do not have an Opengear Resilience Gateway will now receive one.

“Finally, we have an enterprise customer for which we are remotely managing servers, running routers and firewalls in their own environment. We are planning to place the Opengear solution there. It marks the first time we have carried out a deployment of Opengear’s Resilience Gateway outside our own data centres.”

The rapidly expanding use of Opengear at bears witness to the broad benefits it brings the hosting provider and also highlights a partnership that goes from strength to strength today and will look to evolve further in the future. is on a fast growth path and Opengear continues to support its dynamic expansion worldwide.

What the Capital One Hack Means for Financial Networks

One of the largest data breaches ever occurred to one of the largest financial corporations in the country, Capital One. Over the span of two days, more than 100 million Capital One credit card applications were accessed.

The hack occurred in March, however it took months before Capital One was aware of the event. The suspect is Paige Thompson, a 33 year old, former software engineer from Amazon Web Services. By exploiting a misconfigured web application firewall, she was able to access the Amazon server hosting Capital One’s customer information. After hacking into the organization’s server, it wasn’t until July 17, that a tipster informed Capital One of the existence of the stolen information.1 Thompson gained access to credit scores, balances and addresses, along with:

  • 140,000 Social security numbers
  • 1 Million Canadian social insurance numbers
  • 80,000 Bank account numbers

Prevalence of Cyber Attacks

Finance is one of the top targeted industries when it comes to cyber-attacks. These types of institutions have a steady stream of sensitive customer information being entered into their databases making them an ideal target for hackers. Letitia James, General Attorney of New York was asked about the Capital One breach and stated, “It has become far too commonplace that financial institutions are susceptible to hacks, which raises questions like, why are these breaches occurring? Are companies doing enough to prevent future data breaches?

Dangers of Cyber Attacks in Finance

Just last year, more than 2 billion people were affected by data breaches and over the past decade some of the largest attacks have occurred with well known financial organizations such as JP Morgan Chase, Equifax and Citi Financial.2

Not only do these cyber attacks pose as a danger to customers, it also threatens the stability of a network. Downtime causes:

Lost Opportunities

Banks depend on the network for a multitude of reasons such as making transactions, transferring funds or processing applications. Not being able to complete such actions can lead to loss of customers and revenue.

Non-Compliance Fines

Highly regulated industries such as finance, have a large number of regulations to comply with in regards to global privacy, data and security. Any type of network downtime can cause non-compliance and result with million dollar fines.

Extending Your Reach

Many times, these types of disruptions occur in a remote branch, where without the proper solutions, network engineers don’t have the ability to quickly diagnose and remediate the issue. During a cyber attack, visibility is a necessity.

Opengear devices extend your reach, providing full visibility to remote sites. Smart Out-of-Band and Failover to Cellular enable engineers to securely access the network and continue to run applications needed to ensure business continuity while the issue is diagnosed. Providing a wide range of capabilities such as the ability to disable access to the impacted network equipment, disconnect the WAN connection to isolate an affected branch and even reconfigure devices to factory default, Opengear devices ensure that normal business operations aren’t effected by a cyber attack.

As these attacks continue to evolve, the likelihood that your bank may be affected increases.

Top 5 Things You Need For Network Resilience

It’s now officially 2019. The year of network resilience? That’s where we come in. To ensure that your data center is up and running for the new year, we have the top 5 things that you need.

1. Automation

Anshul Sadana of Adobe said it perfectly – the number of engineers that run a the network doesn’t need to grow with the number of network devices they manage – this is because of automation1. Inside data centers, branch locations and even during  SD-WAN deployments there can be thousands of moving parts. In order for solutions to run seamlessly automation is needed. This ensures that these parts continue to move with as little manual intervention as possible, meaning less error.

2. Monitoring

As more data centers and remote sites pop up, the ability to have eyes monitoring every device is impossible. Network outages are a very real part of branch offices and can be caused by many variables like a manual error, temperature issues or the old backhoe cutting through a fiber. All of these things which may seem small can have a large impact. The average cost of downtime is $5,600 per minute according to Gartner. Smart Out-of-Band (Smart OOB™) allows organizations to have eyes at every site, setting automated alerts through email or SMS to notify of an issue; and link to environmental sensors for temperature, humidity and door openings. This provides the ability to manage the infrastructure remotely and enables troubleshooting and remediation at the network edge. This then ensures that infrastructure can be accessed even during a system or network outage.

3. Speed

It’s a guarantee that in 2019, cloud providers will deploy more data centers that will need to be larger scale. How will these be built and deployed quickly enough to meet the market demand? Zero Touch Provisioning (ZTP). This process is when managed devices in their unconfigured state request and are delivered initial setup resources through the local management network. What does this mean for network engineers? It means the provisioning process becomes automated so there is less need for manual intervention and skilled technicians.

4. Edge Computing

The increase of IoT technologies are creating a need for information to be processed closer to the edge2. The edge lightens the load on central servers and response times are fast. Network engineers understand that this is considered the new computing architecture that will distribute resources for millions or even billions of different devices and locations. Edge computing distributes the support necessary to meet the increasing need for services and applications because the data is processed is closer to the end user.


SD-WAN deployments are increasing in popularity. Eliminating the need for expensive MPLS circuits and maintaining secure network connections, these deployments allow network engineers to utilize and aggregate high bandwidth internet connections. When paired with Smart Out-of-Band, organizations are able to ensure the network can be accessed during an outage remotely.

Ensure that your data center is secure and resilient in 2019. Opengear is constantly evolving our solutions to meet your needs.  Read our white paper to learn more.



Network Resilience: An Extreme Case of Remote Network Management

Network Resilience: An Extreme Case of Remote Network Management

What Does the Growth of IoT Mean for IT Infrastructure?

Railroads have a unique set of challenges when establishing network resilience, these include regulatory restrictions, safety standards and compliance. In an effort to resolve these, a Class 1 Railroad decided to approach Opengear to discuss remote network management for their organization.

Thousands of miles of track and hundreds of monitoring stations across the United States poses a challenge when connecting network devices. The railroad was losing network connectivity and flying blind when it came to scheduling, maintenance and track switches. To monitor and maintain connectivity, the organization tested Opengear’s solution for cellular out-of-band capabilities.

For 6 months, the railroad rigorously tested the ACM7004-2-LMV with built in cellular. To ensure that the devices met their requirements, could perform in extreme environments without interruptions from vibrations and was able to be easily used by network administrators, the devices network resilience capabilities were tested.

Once testing was completed, Opengear’s devices were the clear solution. The railroad deployed the Resilience Gateway at each of their key locations, resulting with over 150 units across their network.  The anticipated result is to reduce truck rolls by 50%, repair connectivity in a matter of minutes and ensure network resilience.

The Cost of Network Resilience

You may have noticed that we tend to bang on about the ROI of our solutions.  But it’s not without good reason – when your alternative is a rude wake up call followed by a 3am drive to the data center, all while the downtime bill racks up and your customers scream, deploying Opengear remote management makes for a very attractive proposition.

Perhaps not surprisingly, we tend not to focus on the other side of the equation.  The cost of not having network resilience is clear, but what’s the cost to have it?

Running the numbers

The initial capital outlay is easy to calculate, once you’ve worked out how many sites and devices you’re managing.  With our intuitive product interfaces (no certifications needed!) and industry leading, free technical support, it’s fair to say the cost of adopting Opengear is minimal.

Ongoing operational costs take a bit more figuring out.  For starters there’s your cellular data plan, which can be a little as $5/month/site – a bargain vs. traditional phone lines.

But we’re skirting around the real issue here – when you deploy out-of-band, you’re deploying a secondary infrastructure, and in many cases an entire secondary network.  This means more network endpoints to maintain and more network complexity to manage.

The hidden costs of resilience

When you’re up to your eyeballs managing a production network, the last thing you want on your plate is more work managing your out-of-band network.  (Actually the last thing you want is a remote outage where you haven’t deployed Opengear yet!  Sorry couldn’t resist.)

Manually configuring and installing console servers one-by-one is time consuming and not particularly fun.  Plus it’s the kind of task that tends to get delegated to a relatively inexperienced junior network admin or contracted remote hands, making it all the more prone to human error.

And when network operators need access to a remote router that’s gone dark, are they fully trained to determine the network state, connect either to the Opengear unit’s primary or backup cellular IP address (assuming there’s no carrier NAT), then start a session to the correct serial port?  You’d hope so.  But in reality, ops don’t necessarily know or even care what a console server is, they just need that router console.

Self-managing remote management

We built Lighthouse 5 Central Management to address these very challenges.

Using Lighthouse Console Gateway, you don’t need to know how the router or switch console is cabled up.  You don’t even need to know how the Opengear unit managing it is connected to Lighthouse – be it in-band, behind a firewall, or tunneling over an insecure public network like the cellular WWAN.   Just type the name of the target device using your preferred SSH client or web browser, and hey presto – you’re connected.  Lighthouse manages the underlying complexity so you don’t have to.

Zero Touch Enrollment extends Opengear’s class-leading Zero Touch Provisioning capabilities, enabling Opengear units to be automatically and completely configured, and securely connected to Lighthouse within minutes.  This redesigned enrollment process even integrates with your AAA servers to automate user permissions management, matching metadata tags to automatically grant access to authorized users.

Finally, with Lighthouse 5’s open, RESTful API you can integrate out-of-band access directly into your monitoring, trouble ticketing and collaboration tools – “there’s a problem with this switch, click here to fix it” – so ops are more efficient than ever.

So while the cost of network resilience can be non-trivial, in Lighthouse 5 we’ve designed a solution that allows you to equip your network for maximum resilience with maximum ROI.  And after all, what price do you put on a good night’s sleep?

Opengear’s Resilient Online Connectivity Enables Research on the Ocean Floor

The Challenge

Nestled on the floor of the of the Pacific Ocean, three miles below the surface, is the ALOHA Cabled Observatory (ACO). Providing real-time oceanographic data, it is used by scientists all over the world, enabling them to conduct experiments under the water – where maintaining a high reliability network connection is critical.

The solution had to meet several criteria:

  • Maintain a flexible and extensible network solution able to adapt to the ACO’s future needs
  • Provide secure connections to control equipment on the ocean floor
  • Stream terabytes of data over a submarine fiber optic cable reliably
  • Ensure resilient connectivity keeping ACO online to collect and transmit data

The Opengear Solution

ACO chose Opengear to provide secure access and resilience. Opengear devices were placed at the AT&T Cable Landing Station on Oahu. Connecting ACO to land by a 147 mile long submarine fiber optic cable that enters through the station, the network equipment manages ACO’s power supply and communications. It also forwards data streams through the University of Hawaii to its Manoa campus.

To provide secure access, Opengear safeguards the connection between the landing station and the data center through an IPsec VPN tunnel. This enables Opengear devices in the data center to contact the station and control resources at the ACO with secure remote access to equipment at the ACO, established from anywhere using an integrated SSL VPN. This ensures that the scientists can easily conduct experiments and maintain security compliance while complying with Federal Information Processing standards. Using Opengear devices, the ACO is also surpassing the Department of Defense requirements for securing unclassified data.

To ensure resilience of ACO sensors, Opengear provides both in-band and Out-of-Band (OOB) control for streaming hydrophone and video data through a high availability failover pair technology of encrypted connections from the AT&T Cable Landing Station to one of the School of Ocean and Earth Science Technology’s (SOEST) data centers.

Opengear’s highly extensible and reliable solution provides resilient connectivity. That with secure access, versatile data management and redundant data storage enables them to plan for future upgrades. Opengear devices safeguard the availability of the underwater connection and the uptime of its land based network and data.

“We’ve all heard of the ‘deep web’, but maintaining the deepest reach of the internet – beneath three miles of water – represents an exciting new frontier and offers a uniquely insightful perspective as we work to better understand our oceans and our planet. We thank Opengear for providing dependable networking solutions for our forays into this underwater frontier.”

– Brian Chee, IT Specialist, University of Hawaii at Manoa

Opengear’s Smart Out-of-Band and redundant failover to cellular technology enables the coordination of computers and devices to offer real time data management. It also helps them achieve redundant copies of all datasets transmitted by the ACO that are stored at different physical locations to ensure safety from disaster.

Aloha Cabled Observatory’s need has been fulfilled and now:

  • Has a high availability connection that ensures secure access to equipment at the ocean floor
  • Can support future expansion of its equipment and capabilities
  • Streams terabytes of data for availability in real time and are redundantly stored at different locations to safeguard against data loss

Scientific Research Customer

The ALOHA Cabled Observatory (ACO) sits on the ocean’s floor, three miles below the water’s surface and sixty miles north of the Hawaiian island of Oahu. The observatory provides real-time oceanographic data using equipment including a hydrophone and pressure sensor, along with instruments for measuring and communicating temperature, salinity, currents, acoustics, and video images. The ACO holds several records associated with its depth: it is the deepest functioning observatory of its kind, the deepest power node on earth, and the deepest extent of the Internet. The data captured and transmitted by these instruments is available to scientists and the public online in real-time.
