Unplanned outage 4 years ago

We’re working to recover from an unplanned maintenance event this evening. This was caused by a problem with one of our database servers. We apologize for the downtime.

Although this outage was unplanned, we’re going to use this time to upgrade the affected database. We’re hopeful this will help with some of the whale blips we’ve seen a couple times this week.

Update (11:53p): We’re still working through this issue and dealing with some timeline inconsistencies (seeing updates from folks you don’t follow).

Update (2:10a): We’re testing to make sure everything is in a good state before bringing the web servers out of maintenance.

Update (2:20a): We’re out of maintenance. You may see updates from users you do not follow. This problem should not recur.
