I suppose this is the correct place to post this, if not I apologize in advance.
I find myself looking at 404 messages more often than new relevant game information lately while on Mmo-champ. This started happening about a month and a half ago and happens several times a day, sometimes for 30+ minutes at a time. However today I got this little gem when I attempted to access the site.
I would check out your hosts file to make sure it hasn't been hijacked (though a part-time hijack would be odd). I'd also do a sweep for any malware on your system. I haven't seen a 404, 502, or any coded error in weeks.
