All that's left here is nagios and releasing thunderbird on firefox infra. For the former, we're keeping dm-nagios01 around until the new nagios server is ready. For the latter, jhopkins said that it will be complete this week and has already talked with Mark Banner and gotten his okay on the impact to the release schedule.
We have working nagios and it's undecided what we will do with that going forward. Removing that as a dependency. Coop indicated that he got the tbird release working last Friday, so calling this bug resolved.
