As a response to a security incident, we will be logging out all users
shortly. [1] We don't think the incident had real-world impact but prefer
to err on the side of security. After considering various aspects (such as
the effect on upcoming software deployments, and finding a time when most
people are asleep), we decided to do this on very short notice. I apologize
for the disruption.

If this causes any unexpected problems (apart from having to log in again),
please report them there.
[1] We have actually done so progressively over the last week, but that
method turned out to be unacceptably slow, and we found a way to do it all
at once.
