This is (finally) done. A handful of instances didn't handle the
suspends properly and had to be rebooted, but everything should be up
and running now. Please let me know if you have instances with new issues.

This didn't go very well, and then I got pulled into a related
emergency[1] (one that was related but largely invisible to users.)
So, I may have another go at the suspending/resuming tomorrow
morning. As before, if we wind up needing to do something more
intrusive than suspend/resume I will provide additional notice.
Sorry about the endless maintenance window :(

Moritz and I will be applying some security patches to the
virtualization hosts tomorrow, beginning at 14:00 UTC. We're going
to try to apply this change via suspend/resume cycles rather than via
reboots -- that means that each VM should experience a minute or two
(or three) of hesitation but should not register any reboots.
If this goes badly and it turns out that actual reboots are
needed I will reschedule the maintenance for a later date with more
notice. For now, though, no action is required from any of you.
