Ya, you can check my forums and normally someone will have posted there about it when it is down. It happens sometimes, but I normally try to get it back up in a timely manor (within a couple of hours). The website is linked in my sig if you don't know it already.
I am not exactly sure what caused it to be removed from the serverlist today, unless my internet might have gone out for a while and came back on it's own, or unless the Login Server was down for a bit. But, it is back up now
