I think bro, there is some issue with ISP so my suggestion is to use VPN.

Same here. I am also not able to access Codeforces using Airtel Cellular network, now I am using my brother's data.

I am also facing the same issue with my Airtel cellular network, however it's working completely fine with other ISP's like Jio, BSNL etc. In the meantime you can use codeforces.cc which is an unofficial mirror for Codeforces.

You can use VPN. BTW I am commenting from my friend's PC. :)

I think there was something wrong from Airtel's side. the problem started 2 hours before the contest started (I was trying to open Codeforces!).

sometimes the website did open but I wasn't able to login (It was getting Timed out again and again).

another thing was that VPN wasn't even working.

RIP, wasn't able to do the contest :(
