It wasn't a restore, it was a recovery. It probably took a long time because of how PM was designed. We're mostly on a 10+ year old architecture -- I'm sure there are plenty of new features in MySQL that we are missing out on. I mean, it's impressive the heavily modified Everything2 engine runs as well as it does now, but I can't say I'm surprised recovering from a critical database issue takes a long time for it. Also, they probably didn't know it would take 48 hours when the recovery process was started.
