Choker, I think it's a good idea but the implementation needs some work.
According to betterbeup, candidhosting has been monitored for approximately 8 months and during that time it has been down 42 hours. Has BBU existed this long? Has candidhosting really been down for 2 days?
I think it's better to group entries by individual site/server, then the aggregate details with less emphasis on whether the webhost itself has been "up" or "down."
