Affected Components: Control Planes for clusters in FES

Scheduled Start: 31. Mar. 2023/07:00 pm Scheduled End: 31. Mar. 2023/09:00 pm

State: ABORTED

Description:

We will replace our load balancer in front of the control planes of MetaKube clusters in the FES region in this maintenance.

Recent incidents indicate that components related to the load balancer may have been corrupted.

Customer Impact during the Maintenance:

During this period, the public IP of the load balancer will change. We do however not expect any disruptions.

The maintenance is only related to clusters in the FES region and on AWS.

Update (08:20 pm):

We had to abort the maintenance after we saw that the new load balancer behaved faulty under load. We reverted to the previous load balancer and the situation is stable. We will investigate the problem further.

Affected Components: MetaKube, region FES

Incident Start: 22st March. 2022/10:45 am

Description:

The load balancer to the cluster control planes did not behave correctly and caused slow or dropped connections.

This in turn caused nodes to show as NotReady and problems for kubernetes controllers in the clusters.

Update at 11:30am

Services are operational again.

Update at 15:15am

The load balancer caused problems again for a few minutes.

Incident over at 15:30

Affected Components: MetaKube Control Plane, region FES

Incident Start: 21st March. 2022/08:30 am

Description:

We're investigating sporadic issues with out MetaKube Control Plane / API in our FES region that may have started already before.

Customer Impact:

Some API commands / changes are not properly executed.

Update: 09:10 am

We created a workaround for an issue in a networking component but affected pods are not restarting automatically, we are triggering that manually.

Update: 09:25 am

Most affected pods have recovered but managing the cluster is still impaired.

Update: 10:13 am

A fix has been implemented but will take some time to be rolled out.

Actions using the Cloud Controller Manager (i.e. creating Load Balancers, getting IPs for Nodes...) do not yet work for the affected clusters.

Update: 12:38 pm

The fix has been rolled out and clusters are running as expected again.
