During this maintenance, we will perform firmware upgrades on our border routers in CZ41 and ES34. Thanks to our redundant network design, we expect only brief traffic disruptions and possibly increased latency.

Customers connected directly to the affected devices have been informed by email about the expected outage window.

During our maintenance window, we will perform configuration changes on our routers and switches in ES34 NTT in the managed and colocation segments. Thanks to our redundant network design, we expect only brief traffic disruptions and possibly increased latency.

During our maintenance window, we will perform configuration changes on our routers and switches in CZ41 and CZ42 in the managed and root segments. Thanks to our redundant network design, we expect only brief traffic disruptions and possibly increased latency.

During this maintenance, we will perform firmware upgrades on our border routers in CZ42 and ES34. Thanks to our redundant network design, we expect only brief traffic disruptions and possibly increased latency.

The scheduled maintenance is now underway. We'll keep you updated on our progress.

The maintenance is now complete. Thanks for your patience.

We are currently experiencing a network incident that may cause connectivity issues and affect the availability of our services. Reason is an unexpected router restart triggered a failover, leading to intermittent availability.

All systems are up and running again.

We will perform maintenance on our backbone fiber infrastructure. Due to our redundant network design, we do not expect any service impact. During the maintenance window, however, network redundancy will be reduced.

Customers with affected CWDM wavelengths have been notified separately.

The scheduled maintenance is now underway. We'll keep you updated on our progress.

The maintenance is now complete. Thanks for your patience.

We are currently experiencing a network incident that may cause connectivity issues and affect the availability of our services. Reason is an unexpected router restart triggered a failover, leading to intermittent availability. Services are recovering and we're validating that everything is back to normal.

Affected is location NTT / ES34 for the segment Colocation.

All systems are up and running again.

We are currently experiencing a network incident that may cause connectivity issues and affect the availability of our services. Our team is looking into it, and we will provide an update as soon as we know more.

Thank you for your patience.

We've identified the cause: an unexpected router restart triggered a failover, leading to intermittent availability. Services are recovering and we're validating that everything is back to normal. We'll confirm once fully resolved.

This incident is resolved. We no longer see any impact and all services are operating normally. Thanks for your patience.

During the NKE control plane issues from Monday to Tuesday night, we disabled parts of our network redundancy handling traffic for Managed Kubernetes and Deploio, as we suspected it was the cause of the issues following the network upgrades. We will re-enable the redundancy today, starting at 21:00 CEST.

This can lead to short traffic disruptions and possibly higher latency. We will monitor the situation closely during that time to make sure everything works as expected.

The scheduled maintenance is now underway. We'll keep you updated on our progress.

Enabling the redundant paths unfortunately led to another outage, larger than we expected, affecting some services. This time we may have found the root cause in the network. Services should be recovered now.

Please accept our sincere apologies for this. We will work with our equipment vendor again to determine why this happened.

Due to some unforseen errors in the maintenance window, NKE Control clusters might not be reachable. If you are affected, you cannot log into your cluster, see the status of your cluster or schedule new workloads. However, existing workloads are still reachable.

We are working on a fix.

New Worker nodes cannot be spawned currently we are still working the fix

The core issues have been identified, we are expecting all services to recover fully right now.

We've now resolved the incident. Thanks for your patience.

After consulting our network vendor's TAC, we will upgrade the firmware on all devices in the NTT ES34 Managed Segment. The new release should fix the root cause of the crashes we have seen on one of the routers in this network fabric.

During the upgrade we expect a temporary loss of redundancy, short traffic disruptions and possibly higher latency.

The scheduled maintenance is now underway. We'll keep you updated on our progress.

The upgrade took longer than anticipated due to some issues. We now need to replace one network device and therefore have to extend the maintenance window beyond 03:00 CEST.

The network maintenance is now complete. The defective device was replaced. Thanks for your patience.
