Seriously, does this guy just not pay his fucking bill every month? We get bad gateways sometime between the 13th and 16th of EVERY MONTH. Sure, we'll get one on another date every so often but it's a guaratee we get one in a three or four day window.
Right now all portions of this site on the server are being checked. I need to let the developer know when, if it happens again. So the down time seems to be postponed. And when it happens, I'll try to find out approximately how long it will be down so you'll have a decent expectation.
