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@lists.wikimedia.org [1] mailing list.
regards.

This is starting right now!
