MikeMirzayanov's blog

By MikeMirzayanov, 6 weeks ago, In English

Hello!

Over the past few days, I've received reports that Cloudflare is sometimes blocking completely legitimate actions by regular users.

I've already figured out some of the reasons for this (I think it's better now). However, it would be helpful if, in such cases, you could leave a comment here in the format: "URL : Ray ID : description of the action." For example: "https://mirror.codeforces.com/contest/2001/submit : 8b7fd4274bc1c315 : just tried to submit a solution."

I believe that if we gather such incidents, we can quickly eliminate this unwanted behavior.

After removing some shortcuts I succeeded to submit my problem but before that I received this alert : ""Sorry, you have been blocked" .

      Why Codeforces want to block bots to submit codes?

      I tried to submit a solution and cloudflare shows "You have been blocked". At the bottom of this page, I got the Ray ID.

UPD: It seems we don't have a large number of issues with this. But thanks to everyone who reported: I've applied one more reconfiguration and hope to see even fewer (or almost none) reports now.
