Why do the ratings take ages to update in some rounds? Ratings of round 685, 686 and 687 haven't been updated since so many days.

Hello guys!

In yesterday's round Codeforces Round #617 (Div. 3), in question 1296C - Yet Another Walking Robot, I submitted this solution using map which took 61ms to pass: 70273184. Today, I thought of submitting the same solution using unordered map, which I later found out doesn't have a hash function for pairs, so I copied the hash function from GeeksForGeeks and then submitted the solution which took 187ms to pass: 70355416.

Can somebody tell me why is unordered map working slower than map for this problem ?

Thanks.
