Affected wikis have been notified and it's been added to the next issue of Tech News, which will go out on Monday.

I've also pinged @Jseddon and @Trizek-WMF with a (time-wise) very brief CentralNotice banner request. The communication plan looks like this:

  • Village Pump posts for affected wikis (5 March)
  • Tech News announcement (11 March)
  • CentralNotice banner (pending approval) (19 March, for 25 minutes)

Tech News delivered; @Trizek-WMF has agreed to put up the banner and I've written the text to be used.

Thanks @Johan!
Can you let me know the link so I can include it on the read-only message the day of the maintenance?
Thank you!

I've sent out a request for translations.
