I think I can start breathing again.
JDLand.com runs on a shared server, and late last week one of the other sites on the server must have made someone veeeery angry, because a Denial of Service attack was launched that ran until Monday evening. On Monday morning, I decided it was time to get off that rickety server and into a new shared environment (with the same company), but it took another 24 hours for them to get me my files from the old server.
I have no doubt there are still bugs to be squashed, and I will be spending my day looking for them.
In the meantime, thanks for everyone's patience. I know it didn't matter anywhere near as much to you readers as it mattered to me, but I hated knowing how annoying it was to come to the site and have it not respond.
Hopefully things will be back to normal now. Though as long as I stay in a shared environment (which is about four times less expensive than getting a virtual private server), these sorts of things can happen.
UPDATE: A few things are not yet back to life--the RSS feed, the little box on the home page showing the most recent comments, and an updated Permits/Crime list. Otherwise, so far, the move itself hasn't been too bad, other than the very sore jaw from five days of clenching my teeth.
UPDATE II: The above lingering items are now fixed. I imagine there's still other stuff somewhere that's not working, but nothing leaping out at the moment.
