why i am seeing this(ie “503 Service Temporarily Unavailable”) message on my browser when i am trying opening discussion forum.
It’s just some technical difficulties. Try reloading and you will get the page.
It occurs probably because of too much load on the server.
the problem isn’t from your side it is from codechef site being overloaded since the competition that night …just reload 3-4 times and the request goes through
This is a technical or server problem. Please close your browser wait some time and try again.
