Description

x1 primary database needs to be restarted - technical task: T281212
During the restart time (expected to be around 60 seconds or so) all the components and extensions that use this cluster will be read-only.
Things that might experience some issues when creating new writes:

  • New short urls cannot be created
  • Email bounces from lists might not get recorded
  • There might be issues with new translations
  • New items on the notification list might fail
  • Reading lists might not record new items added to "bookmark" or "read it later" feature

Impact: x1 will be on read-only for around 1 minute. Writes will not go through but reads will remain unaffected
When: Wednesday 5th May at 06:00 AM UTC

Just wanted to note that I announced this read-only to the following wikis: enwiki, commons, tawiki, tawiktionary, tawikiquote, meta-wiki (linking the changes for easy reference).

The standard "read only" banned is misleading in this case - the window will not be preventing edits, just a couple of other actions (see task description) - is it too late to clarify this?

Since its too late to get a good and short wording of what will actually be stopped, can I just suggest removing the "During this time you might not be able to save any edits." message from the banner?

"During this time you might not be able to save any edits." is correct since tools like ContentTranslation would not work. We also used the generic message to avoir to have a new message that would need translations. The one we have now covers a lot of languages. :)
