Hi CommRel,
We are planning the datacenter switchback for the week of April 24th, 2023 (week 17) with the following schedule:
* Services: [[ https://zonestamp.toolforge.org/1682431244 | Tuesday, April 25th, 2023 14:00 UTC ]]
* MediaWiki: [[ https://zonestamp.toolforge.org/1682517627 | Wednesday, April 26th, 2023 14:00 UTC ]] **this is the read only**
FYI, the March 2023 switchover resulted in 119 seconds of read-only time.
Sorry for the shorter than usual notice, if it's too short we may be able to push it back a little.
Thanks!
