I just finished the transition of this blog (and other domains owned by me and Susana) from a server hosted at home to a proper server at a hosting facility, shared with our friends Annie and Tadek. Everything seems to have gone well, including migration of web and mail services. There shouldn’t be any visible changes (other than vastly improved bandwidth) but if you find anything broken, please let me know.
As an aside, I think one of the really cool things of system administration is being able to do a fairly complex change (like in this case, switching hardware, physical location, underlying Linux distribution, etc.) without the users of the services you provide (we provide webmail service to a few people in our families) even noticing.
