Apologies for the outage on phpc.social. Bit of an order-of-operations issue when attempting to start the Mastodon 4.2.0 upgrade. On the next attempt, we'll run OS package updates well *before* attempting the other parts of the upgrade.
Queues are catching up from the outage. Once those are caught up, I'll reindex search; we restored from a backup on the app server (database/Redis/file storage were not affected) so search will be a bit behind 'til we get that complete.
