But do we really care about whether a machine fails? I'd rather say that what we want to minimize is the _service_ downtime. If someone has to take time out from other work to fix it then we care. There are lots of things that we would like to have done but which are not being done due to lack of time. Do we really want to take more time away from other important tasks just to have super-reliable @debian.org email? With one machine, the possibility of the service being unavailable is 0.1. With two machines it's equal to the possibility of both machines failing at the same time, so it's 0.1*0.1 == 0.01, as long as the possibilites are independent (not sure if that's the right translation of the term). Correct. Configuration errors and software bugs can put two machines offline just as easily as one. Otherwise, I'd say that the increase of availability is worth the additional debugging effort :-) Are you going to be involved in doing the work? This entire thread started because the admin team doesn't seem to have enough time to do all the work that people would like them to do.

Runing Bind under User Bind
