Whoa, something just happened to knock us offline instead of being in read-only.

We're investigating that outage while also trying to wrap up our scheduled maintenance. We're working on it.

Reminder that we have some scheduled maintenance starting in a little over an hour. The site will be read-only while we work.

Full functionality on Mathematics is restored. Now the fun begins: determine how it happened, and make sure it doesn't happen again.
