I'll give Network Solutions this much: their phone number is prominently displayed on their customer contact page, and a chirpy operator answered my call after about one minute of holding and cheerfully accepted a stack of money in exchange for a nine-year renewal. (I don't think it's going to take nine years to finish the story though. At least, I hope not...) So MoS and all the rest of it ought to be back as soon as the DNS propagates, within 24 hours at most.
The comic, therefore, will be updated tomorrow when there's a site to update it on! And thanks for the worried emails asking where MoS went, which were a big ego-boost and also a, uh, useful reminder.
(Lessons learned: keep your DNS contact information up to date. Dang.)
