There was a brief (about 5 minutes) interruption in service at about
15:15 EST for the main web server today while we replaced the batteries
in our power backup systems. This was almost certainly un-noticed
as the duration was so short it didn't even trip the automatic failover
systems. But if you happened to try to access any of the web
services during that window you would have received an error message
saying "unable to connect to server."
Additionally, you may have experienced temporary e-mail delivery
failures in the last couple days. During this period we have been
performing an in place Operating System upgrade on our servers.
E-mail delivery was affected by each of the module upgrades for Perl,
Sendmail, Python, and Spamassassin. These e-mail delivery
were temporary in nature and the message will have been delivered
automatically typically within an hour of the e-mail system returning
to the 'accepting messages' state.
