This 1-2 weeks, '502 Bad Gateway' appeared when I am surfing on this forum, but it will like for few minutes or less, then back to normal.
But it happens like few times a day now.
Just want to ask is this only happened on mine...
it has never happened to me as far as i can remember, maybe i am not active enough but you should try surfing with a proxy and see if the problem solves itself
