Cogent Network Maintenance – March 12th, 2025

Services Affected:​ Chicago, Illinois Data Center
Start Date:​ March 12th, 2025 @ 5:01 AM UTC
Estimated End Date:​ March 12th, 2025 @ 7:00 AM UTC

Summary​: Cogent Communications, one of our Tier 1 carriers in Chicago, will be performing maintenance in the dawn hours of 3/12/25. This maintenance has been scheduled to perform upgrades to the equipment in the facility.

Impact on Customer:​ Cogent has communicated that they do expect service to be impacted. As a result, our network team has been moving traffic away from Cogent and onto our redundant up streams all day. We are still in the process of doing this, so please note that disruptions may be encountered, but this is necessary to ensure no disruptions during the maintenance.

Updates:​ We will be providing updates on our [status page](https://status.prism-host.com). To keep up to date, please subscribe to updates & you will be notified.

We have been informed that Path ​Miami​ has been ​brought fully online​ today. ​Chicago​ is also expected to ​come online very soon​ and we have requested for it to come back online closer to ​off-peak hours​ to avoid serious interruptions.

You will notice a ​full outage​ while ​Path brings up Chicago​ and we are routed back onto Chicago. However ​after Chicago is brought up latency will start normalizing​ again as we will no longer be routed to different PoPs!

Hello everyone, our network team ​has identified the root cause of the frequent short drops​ that have plagued the network over the past few days. We understand the ​severity​ of these drops and have ​identified the root cause​. To ​permanently resolve these issues​, we will be conducting ​emergency maintenance​ at ​9:00 AM Central Time​. During this maintenance, you will experience ​brief disruptions​ as mass changes will be done. We apologize in advance for any inconvenience this may pose to you, especially over these past few weeks where we have suffered instability from one of our upstream providers as well as the network maintenance we conducted to upgrade our core late last month. To be frank, the timing could not have been worse.

For transparency, the issue stems from a ​Layer 2​ issue inside our ​VXLAN-EVPN​ network, which is affecting our spine switches that ​processes essentially all traffic on our network​. As a result, this was felt widespread and not just related to one upstream or one cabinet. This issue appears to have sprung from the preparation of on-boarding our on-prem protection suite into our core. We have been working at a fast pace to get that online and operational in hopes of shifting all traffic over in order to provide stability.

We know the past few weeks have been difficult, and we recognize the ​importance of a reliable network​ for our customers and are tirelessly working to improve our offerings.

As we have ​completed maintenance for today​, this extension saw no external loss to production switches. We have made ​a lot of real, meaningful progress today​. We are around the home stretch now, simply a few things to tidy up before we push ​more live traffic​ to onsite!

We will be ​continuing our work​ again tomorrow at ​9:00 AM Central​ to avoid any potential interruptions during peak hours.

At specifically ​9AM Central Time​ we will be continuing development with our onsite network. We apologize for any interruptions this may cause, we are doing this early in the AM to ensure we impact as little traffic as possible.

We understand the frequent issues from upstream isn't making this an easy pill to swallow, but we must continue work on this to ensure we are independent from future network issues once Onsite goes live.

To give context on what onsite will bring for those who may have missed it:

Our Onsite DDoS Protection will allow us to have a ​localized Path environment​ that will be ​isolated​ from the ​global network​. This will allow us to attempt to seamlessly, ​without dropping traffic​ move between the global network and local network when needed.

Take for example the issues that we have been facing now, these are all from the ​global network​ with Onsite we would be-able to ​push traffic onto our local mitigation stack​, effectively isolating us from global network issues, ensuring full uptime. ​This also works in reverse​, if the local network was to go offline for some reason, we would route back onto the global network, while again attempting to not drop any traffic.

This system is ​extremely complex​, and has been under development for a while now, we are speeding up progress but also doing so at the least impactful times, we understand no downtime is ideal, however this must be done in order to ensure we have a fully redundant network. I am sure everyone is tired of these upstream issues, we are too, and we truly believe onsite is the solution we are all looking for.

Warm Regards,
Prism Host
