Hello everyone,
I don’t usually repost WG stuff “as is”, but this shouldn’t “disappear”, because it’s a nice explanation of what happened and happens even now. So, what do you think about this?
Dear Commanders!
The last couple of weekends have presented both you and us with some very high packet loss and latency issues while playing World of Tanks in the late afternoon and evening. In response to these problems, our engineers have been working around the clock and we have put in place several measures to increase the network performance at our end. We understand how disruptive these issues have been for your gameplay and we would like to apologise for the inconvenience caused to you!
