I think our servers just entered the twilight zone or something...

At roughly 0400 GMT the internet facing network interface on db2
stopped talking to the world. The consequence of that would have
been that the bulk upload and tiles at home would have started failing
and normal API requests would have been forced through a smaller
number of daemons than normal although given the time of day it
doesn't seem to have too much effect on that.

I accessed db2 via the internal interface and rebooted it shortly
before 0900 GMT after somebody advised on IRC that it appeared to
be down. I assumed at that point that everything was OK again.

When I saw your email I had a look and found that at 0735 GMT the
mysql daemon on the database server had decided to shut down for
reasons that are not at all clear - it looks from the logs like a
clean shutdown rather than a crash but there was nobody logged in
at the time.

The database was restarted at 0910 GMT and everything looks like
it is running OK again now.
