hmm bad gateway error is usually common on internet,but since im almost always logged in to site,i have noticed sometimes ,connection to site is lost during some hours of day, i did not say anything before,because error 504 is not usually a major issue , but it has happened to me few times, and it seems stopper also have seen the problem(it wud be helpful if more people who get this problem reports it, with any detail they can give)
also sometimes i have found the other most common error of internet "network time out".
since this has happened more than about 3-4 now i think it "may" be related to website , instead of my ISP
