Hey everyone,

Terribly sorry about the short notice – this is not a planned thing, it's an emergency fix. Most wikis (but not the biggest ones) will be read-only for up to 30 minutes at 07:00 UTC AM tomorrow, 17 January. Depending on your time zone, that might be late 16 January. It'll probably be shorter than 30 minutes.

There's a Phab task here with more information and a list of affected wikis: https://phabricator.wikimedia.org/T213858

That list is very long, so to make it easier, I've put a list of wikis that are *not* affected here: https://meta.wikimedia.org/wiki/User:Johan_(WMF)/201901ReadOnlyPage

Please help spread this in your community, if it's affected.
