Perhaps I worry too soon. Apparently, the people running the graphicsmash.com hosting site has paid their fee and all of the strips there are up once more. So maybe the situation isn't so dire as I believed, and maybe I don't have to worry about my host disappearing from under me.

Still, the fact that they waited so long to renew the domain -- a few days after it had expired -- does not speak well to either professionality or financial soundness. Perhaps I should continue to keep a tight watch on those future expiration dates, and think more seriously about a new host.
