There has been an issue with my Nameservers for the past several days, which resulted in some (but not all) of the sites on my machine being unreachable by the world. Repeated contacts with Alex and Tina at the Help Desk made it clear that my problem could not easily be reproduced from there, and it looked very much as if they couldn't fix it. But they stuck with me on it, eventually calling in Dick DeVance to help.
