This upgrade is now complete. The cluster should be stable now. Thank you for your
patience if there were any noticeable interruptions.

Hi there!
Today 2020-12-10 @ 15:30 UTC we will perform an upgrade of the Toolforge kubernetes
cluster [0].
We don't expect any major disruption of the service, but we detected in past upgrades
that some components might be restarted, causing brief interruptions of network flows.
Given the amount of worker nodes we have, more than 50, the operation will take us at
least a couple of hours.
Tools maintainers: you don't have to do anything during this operation, but if you
detect anything weird please contact us either in the phabricator task [0], in the IRC
channel #wikimedia-cloud or in the cloud(a)lists.wikimedia.org [1] mailing list.
regards.
