Two days ago I could not submit any solution unless I get the error "Ooops! Something has gone wrong in Codeforces. Do not panic, [...]" (that one with the funny "All your bug are belong to me!"), I couldn't read any statements and I always got the error "Oops! Probably Codeforces can't be reached right now or [...]" unless I was not logged in (I used a different browser "Librewolf" for that, I normally use "Firefox"). Everything else works perfectly fine all the time. Today, 9 hours ago I encountered the same problem.

Probably is just that CF servers were down those two times, but I am writing this entry just in case the problem is local and maybe someone can help me. What can I do to solve the problem?
