I get those frequently...probably at least once every other day. Usually I come back in five minutes with no problem. I just assumed that Revolver had set the server to pick on me since I don't like hip-hop, TV analysts or tattoos.
I must've made an error in the programming logic that was meant to do this only to you.
As to the larger problem, I contacted the provider and they told me to call them when it is happening and they will look into it. My answer was that it's random. Basically the feeling I got was that we are going to have to wait for it to happen for an extended period of time before it can be fixed. That may never happen. If they can't fix it I guess I will eventually have to move to another provider.
