An update on lag issues.

Quote World of Tanks is not just a great game, it’s also a complex client-server application in which the client (installed on your PC) and server (hardware cluster in a data center) exchange data packets with each other. These packets contain information such as the position of your vehicle on the map, shots fired, and computations for penetration and damage. The majority of calculations related to the game mechanics of World of Tanks are server-side, thus significantly limiting the possibility of any cheating and hacking.
The Journey of Your Internet Packets
To navigate the Internet, with its millions of nodes, a packet must travel through many intermediate network systems (including routers, bridges, and gateways) before it reaches its final destination.
The three main routes packets go through on their way from your PC to our game server are:
1) Your local Internet Service Provider (ISP), which provides your access to the Internet using copper, wireless, or fiber-optic connections. In some cases, changing your ISP may be the only solution for severe connection issues.
2) The regional Backbone provider supplies access to high-speed transmission lines that connect users and/or local ISPs to the Internet. These lines form the backbone of the Internet and are the true “Information Superhighway.”
3) Our Data Center houses the computer systems and associated components, such as telecommunications and storage systems, that power our end of the game. This includes redundant or backup power supplies and data communications connections.
If any of the equipment en route is not functioning properly or is overloaded, this can lead to data transmission delay or packet loss. Packet loss occurs when one or more packets of data traveling across a computer network fail to reach their destination.
When caused by network problems, lost or dropped packets can result in highly noticeable performance issues, including lag. Because of this lag, game information received from the server is delayed, and you may not see any changes taking place on the battlefield. This is what leads to the appearance of vehicles teleporting across the map, delays in firing, etc.
If you experience heavy lag, we recommend that you find your “trace route” to our game server. In Windows, start a Command Prompt (Start -> Run -> cmd), then type “tracert 174.34.231.132”. This should also work for any third-party tracking application. Send the results to our Support Services by opening a support ticket. We are grateful for your cooperation and patience in helping us resolve these issues.
Release 6.4 and Recent Lags on the US Server
The recent release of the version 0.6.4 update has led to an increase in the amount of traffic which affected our previously stable network connections. The lag issue on the US server is local, however it does affect a large part of the Eastern United States (and all related traffic that goes through it). The servers in our data center are working fine and their capacity is sufficient for the time being.
The first reports of severe lag were received on May 19th, and we started investigating the issue both in our data center in North Carolina and along the packet routes to it, paying special attention to those going through the CaroNet Hosting network. As a result of the analysis, CaroNet made some changes to outbound traffic parameters on May 20th to exclude routes via Level3 (another service provider). On our end, we have reconfigured the server equipment several times so as to optimize the traffic structure and flow, and to minimize the load on local ISPs, reducing packet loss and ensuring as smooth gameplay as possible. The improvement is still partial pending routing issues to be sorted out by the backbone provider at the earliest possible date.
We apologize for the recent lag issues and any inconvenience caused. Thank you for your understanding and support.
