Connectivity issues in Frankfurt due to cooling failure at Equinix FR5

Incident Report for Clouvider

Resolved

As per GTT:
"Service restoration has now been completed following the return of normal environmental conditions within the affected data center area. The improved temperatures allowed our engineering teams to safely restore the remaining affected network interfaces, resulting in the recovery of all previously impacted services. All services have been restored since 14:15 UTC, and no further issues have been observed.
At this time, service stability has been confirmed, the incident is considered resolved."

We have restored GTT to our mix in Frankfurt.

Update

As per GTT:
“Further investigation is ongoing in collaboration with the site owner's specialist teams, who continue to work on resolving the cooling system issue. Following an initial period of stabilization, the issue has reoccurred and is currently impacting environmental conditions within the affected area. We are closely monitoring equipment temperatures and maintaining continuous engagement with the site owner, with the incident receiving the highest level of escalation. Access to the affected room remains restricted due to safety requirements, which currently prevents direct intervention on the impacted hardware. Our technical teams remain ready to proceed with any necessary corrective actions as soon as safe access is restored.”

While GTT remains excluded from our bandwidth mix in Frankfurt until the resolution, it is imperative to note other carriers at Equinix FR5 might be affected by similar problems.

We continue to monitor.

Monitoring

We have successfully eliminated GTT from our carrier mix in Frankfurt. There's sufficient capacity with remaining carriers to cover our peak traffic in that metro.
We are continuing to monitor the situation.

Investigating

One of our carriers, GTT, is reporting that they are having a core router outage in Frankfurt at Equinix FR5 due to high ambient temperatures.
GTT reports that the access to the room with their equipment is currently restricted.

While Clouvider does not have live equipment at Equinix FR5, many of our carriers are located in that location. Equinix ecosystem in Frankfurt metro relies on campus cross connects meaning the carrier needs to be in just one of the campus buildings to be reachable to all tenants on campus.

After the initial sudden dip in traffic, the connectivity has re-routed around the affected connection automatically. W are now taking manual actions to disable GTT until their Frankfurt core is fully operational.
It is important to note that multiple (but not all) of our carriers are based in Equinix FR5 as such the impact can expand to other transit providers. We'll be monitoring the situation.
