I just checked battlelog and look like bf4 is a dead game. idk what happened, last i played, there were full 64p servers. Also something seems to be wrong with routing to Hong Kong. Used to be under 120ms to Hong Kong now around 180ms.
sent a friend request on origin @rajan20
Did you get any response from Airtel @rajan20 ?
More than half of the german servers ping above 250ms and airtel does not seem to be bothered at all. Same thing with selected japnese and russian servers. Meanwhile, other servers from these same regions ping under 150ms.
Airtel is a very big ISP, i'm surprised that more people aren't complaining about this.
