Recently when I enter to the Codeforces it automatically redirects me to this website https://codeforces.net/?f0a28=1. It were not happening around one week ago. Also Educational Round 91 cancelled due system failure. I don't know, but there can be something between these.
This happens to me too, maybe their servers are doing a workaround because of the meltdown on 91
Nope, for me it was happening before 91 meltdown
Funny I didn't notice it until after
For me it happened when I open codeforces.com in the incognito mode in my browser. But if I open second window in incognito mode, it doesn't redirect me. If I close these incognito windows and open new, it redirects me again. I don't know why.
I noticed it too, but it seems to have been corrected now.
Maybe it was some sort of an interim patch they had applied, while they fixed the problem. Hope all works fine from now on.
I saw it happen for the first time to me just 2 mins ago.
