Hello, as you may or may not already know there will be a datacentre switch back to Eqiad, WMF's main data centre, on May 3rd at approximately 14:00 UTC. For approximately 20-30 minutes you will NOT be able to save edits to any WMF project. If you have any questions feel free to reply back to this email, or ask on IRC on freenode channel #wikimedia-tech. If there any major issues that occur during this time please report them to #wikimedia-tech on freenode!
Thanks, Zppix Volunteer Developer for WMF www.enwp.org/User:Zppix
Would a sitenotice for logged-in users, or at least a watchlist notice, be a good idea?

As there was a globalnotice the other week when we switched to codfw, I'm sure there'll be one this week for the switch back too.
That reminds me that we noticed during switch to codfw that the message shown when trying to really edit a page (the mediawiki read-only message) contains:
The system administrator who locked it offered this explanation: MediaWiki is in read-only mode for maintenance. Please try again in a few minutes
which isn't quite informative. Is there a task for changing the "offered explanation" part? Some hint about the DC switch (and maybe a link to the meta page) would be better.

The read-only messages are controlled by these strings:
https://phabricator.wikimedia.org/source/mediawiki-config/browse/master/wmf-... https://phabricator.wikimedia.org/source/mediawiki-config/browse/master/wmf-...
I think with the pressure of keeping everything up, plus discussing internally if we should declare a specific amount of time (given it doesn't auto-update) we ended up a very generic message. We are, however, looking at showing better error messages like on the ticket I reported at https://phabricator.wikimedia.org/T163455#3199813
Please send a pull request or file a new ticket on Phabricator with the #operations and #codfw-rollout tags with a proposal and we can definitely change it by Wednesday.
Thanks,
Hey, I had a quick chat with Zppix about how to solve this and we ended up creating this task instead of just sending in a patch:
https://phabricator.wikimedia.org/T164177
While it looks quite trivial to change the strings in the config files on the first glance, I noticed that the switchdc script actually hardcodes this message in the scripts used to set mediawiki ro and back rw (maybe also somewhere else, haven't checked), which needs us to pay attention to not break switchdc by exchanging that message. Details are described on the task, let's continue there.

Those variables are in the process to be moved to Etcd to make the configuration dynamic, see [1] and related tasks, hence (re)moving the problem in the first place. Even in the case that this will not go to production in time, the hardcoded part in Switchdc can be easily removed, please find my detailed reply directly in the task in [2].
