Why did the Ranklist for CodeGeeks ( COGE2017 ) Froze ?

I don’t remember the name exactly but this happened with another contest. Why does it happen that the Rank list for a certain contest freezes ?

I think it’s because too many people checking the ranklist at same time :frowning:

Host decides the type of ranklist suitable for the contest.

It was frozen some time back.Now it’s back to normal.
