Saw that a couple times today myself. Page Time: 1.18107 seconds Memory: 22,388 KB Queries: 27 Webserver: 67.225.170.216 Templates: 59For at least the past week there appears to be glitches where the site just locks up for like a 30 or second timeout then you get the 504 gateway error. After the error, the site works fine again. I wonder if it is some sort of hardware glitch like a hard drive trying to remap a sector or something.
It is odd, the site works great for a long period of time, then gets one of the annoying timeout freezes then goes back to working normally again.
