They might have the worst host I've ever heard of. It would take a decent host about 30mins to simply copy their files and database to a working server. Any decent host would have done this for them within the first hour of the outage. A response such as "there's been a hardware failure, we are transferring your data to a new server and we'll have you running again asap" is not at all uncommon. Waiting on parts? wow. I'm sure they'll be switching hosts as soon as they can, and setting up their own off-site backups.
