Frequent 502 Bad Gateway errors after the DDoS attack

Revision en1, by SHZhang2, 2019-10-06 23:59:18

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?
