Hi everyone. I am holding classes on competitive programming and today several of my students are facing problems with registration on codeforces. Specifically, the confirmation email does not arrive (...yes we checked spam). Has anybody else also faced (or maybe is facing now) this issue? We tried to resend email multiple times but that didn't work as well :(

MikeMirzayanov, is it a temporary bug/anti-ddos measure or maybe I am doing something very wrong?
