Today I had a very bad experience. I finished coding 1924C - Фрактальное оригами just a minute before the contest ended and when I tried to submit it, Cloudflare blocked me from doing so (this code got AC 243668438 after the testing phase, so yes, I lost rating because of this). My point is that not all of us can have a god-blessed internet connection, and Cloudflare is annoying, I lose several minutes in every contest because of this and I'm pretty sure I'm not the only one. I have to wait a month between rated contests because the Div1 frequencies are bad so please remove Cloudflare, there must be several ways to prevent DDoS attacks, choose the one that doesn't affect the contestants.MikeMirzayanov
