Last night, the hosting company made a "human error" and deleted a bunch of hosted websites. When they restored from their backup, they discovered that backup was corrupted. They had to go to their offsite backup and that takes some time.
We're up, but with a different ip address that coincidentally was an audio forum. The urls are the same (everything after /forum...), so sometimes you'll see their pages for a few hours or so.
edit: I had Thursday night's database backup, so I could have failed over to another provider. However, I assumed that it would take me longer to set that up than my hosting company could recover RW. And then everyone would have to wait for the new DNS changes.
For the future, I would like to set up either ZoneEdit or CloudFlare to provide a quick fail over to another system. If anyone has experience with that, please offer some advice.
