Hello, as I write this blog its about 30 minutes before the Codeforces Round 984 (Div. 3), and I think I found the bug possibly caused by incoming contest.

Go to this link

Go to "Past contests" section and below you will see links to different pages (example link to page 2)

It redirects me to this link instead.

I'm not sure if this is intended? If this is a known bug or intended feature please kindly inform me, I will delete this blog.
