recently came across a very nice article written by Ultrasonic2 who has authorised to publish in RSR.
Article Summary aka TLDR:
“When you connect to WOT you get assigned any one of many servers/backbone connections. ( In this topic I only talk about 7 but I believe there are much more )
For some users, the servers return Vastly different Pings.
These vastly different pings account for the sometimes you have a good ping and others don’t.
Since the server assignment is random “Fixing” your ping might be as simple as restarting your client and thus connecting to a different server.
This topic is not about people’s pings going up and down during the game that is a given. This is about if your ping in game varying from say 130- 150 or 160 -190
This is not just an NA west thing, East has the same oddity too. I would also suspect that other regions would experience the same thing.
At this point the cause is unknown. Since some users are affected and others aren’t I’m not sure who is to blame for this. I can not say this is a WOT problem or not but I would like someone to take me seriously.
It seems to be a networking issue since using a VPN tool like Mudfish can result in all the servers returning pretty much the same ping.”
