It’s finally happening! 
We need a short downtime to complete the site merge. This will start at 2023-03-03T17:00:00Z, and we expect it to take no longer than three hours.
If you have any problems or questions about the process itself during the downtime, the Ask Fedora matrix channel is a good place to check for updates. Note that that channel isn’t for general Fedora help — see https://matrix.to/#/#fedora:fedoraproject.org for that (or, wait a bit for the site to return!).
If you see any problems or oddities after the merge (and let’s face it — there probably will be!) please report them in Site Help & Feedback. Thanks!
