What is the problem?

Site Reliability engineering would like to do a datacenter switchover as already has done in the past (2017 and 2016).

How can we help you?

We would like to communicate to the community and all other interested parties the switchover's and switchback's timeline and the repercussions of it.

What does success look like?

No complaints from the community about being unaware of the switchover

What is your deadline?

Tentative timeplan currently is. Note that only the mediawiki part is expected to have visible user repercussions as the wikis will need to be in a read-only mode for a while.
