I currently host buildbots for
many of our supported platforms; everything with a 'bot-glyph-*' in front of it on this page: <
http://buildbot.twistedmatrix.com/buildslaves>, and also bot-exarkun-1. So, when I move (at the latest, 6 weeks from now) these will all go offline.
The somewhat less palatable option 3 is to just let much of our build infrastructure be offline for a month.
