About halfway through the contest, this message kept appearing: 
Even m2.codeforces.com isn't safe: 
Note: My internet connection is not broken Did this affect everyone? Anyways, this is extremely annoying and should be fixed as soon as possible. I had to reload my pages many times before Codeforces began functioning again.
I think it's an attempt from Codeforces to redirect you to alt servers in case of the main server being attacked. I think when you have a bad internet connection or something like, it might think that Codeforces is down while it's actually not.
I think Mike commented on the issue before.
