Issues with m1/m2/m3.codeforces.com During Today’s Contest (Site Freeze & Missing Statements)

Revision en2, by Safin17, 2025-06-21 20:23:19

In today’s Codeforces contest, the website was frozen and not working properly during the first 5 minutes.
Also, the subdomains m3.codeforces.com and m1.codeforces.com were not displaying the problem statements — it was showing “The statement is not available”
About 5 minutes after the contest started, I was finally able to access the statements from the main website and began the contest.
Even after around 60 minutes, the m1 and m3 subdomains were still not working. (I didn’t check m2 by then.)

The main website also seemed slow during problem submission.
When I submitted the file for Problem A, it kept loading without showing the status page. I panicked and foolishly, even though m3 wasn’t showing the problem statement , I pasted the same code and submitted it again through m3. But on m3, the submission page was saying "No Data."

After a few minutes, the main site refreshed and I saw two submissions with exactly the same code, but with different languages:

  • C++23 (GCC 14-64, msys2) — submitted via m3
  • C++17 (GCC 7-32) — submitted via the main site

It was foolish of me not to check properly before submitting again — normally, Codeforces doesn’t allow resubmitting the same source code unless the language is different.

These are the submission links:

Because I panicked and submitted twice, I may have lost 50 points due to the resubmission penalty.

Here’s a short screen recording showing the issue with m2 and m3 as well:
