I have only had a few problems with my website (and to be honest, most of them were my fault) but I check the server status in my CPanel daily to see what is going on and the following is the most common problem I see (this one is as of 4:30am PST 2-25-04)
Server Load 5.87 (2 cpus) (red blinking light)
I don't know how to copy the graphics from the screen so I have to type it out..
The only other problem I have seen was a HDD for /home at 97% usage and that was apparently quickly solved as it it now at 46%.
I don't know what server I am on (perhaps you could tell me) but my url is chrispysworld.com
I am not having any problems with my site but I thought I would pass on the status about the Server Load.
Also, since most of the posts here seem to be negative, I thought I would say that of all of the webhosts I have had, you provide the best bandwidth and diskspace for the price you charge.
