After the DDoS attack ended, while Codeforces is accessible again, 502 Bad Gateway errors frequently appear while trying to do so. Refreshing the page for a few times solves the problem temporarily.

Anyone having the same problem? Any explanation of why this happens?

Same issue. I'm also getting the "Sorry it is a DDOS attack. The round will be unrated." message often, and worst of all, I can't see the tests for any submissions (the chrome console just says there's a 503 when trying to load tests).

It seems that the server is being cautious with requests or maybe just going crazy after being attacked.

Maybe Codeforces cache system stored that as well :P
