Hi,

We will be upgrading the Toolforge Kubernetes cluster next Monday (2023-04-03) 
starting at around 10:00 UTC.


The expected impact is that tools running on the Kubernetes cluster will get 
restarted a couple of times over the course of the few hours it takes for us to 
upgrade the entire cluster. The ability to manage tools will remain operational.


Since the version we're upgrading to (1.22) removes a bunch of deprecated 
Kubernetes APIs, tools that use kubectl and raw Kubernetes resources directly 
may want to check that they're on the latest available versions. The vast 
majority of tools that are only using the Jobs framework and/or the webservice 
command are not affected by these changes.




This has been rescheduled to Monday 2023-04-10 to leave room for the other 
operations we have.


regards.

Just to make sure I'm clear, the downtime announced yesterday 

 is still happening?

That's correct, the upcoming downtimes are still happening. These three 
projects are largely unrelated so we're trying to not do them all at the 
same time.
