Bandwidth is a measure of how quickly data can be downloaded and uploaded. When your ISP advertises connection speed - they are talking about bandwidth. I have a high speed connection, so why is my latency so high? If you suspect this is the issue, check those locations first before trying troubleshooting. There is always the possibility that there is a server issue, but we try to post about these problems on the Breaking News bar on the Blizzard Application and In game, and update our BlizzardCS Twitter as soon as we can. (This is why we ask for connection tests when you’re having particularly stubborn connection problems.) If there are any problems between your house and our servers, you’ll usually need to reach out to your ISP to get them resolved. It’s very likely that you take a different path through the internet to connect to our servers, and so comparing two games or services is most likely not relevant. Even two different data centers in the same city may use different peering partners to connect. To add to all of this, everything else that you connect to across the internet is in a different physical location. Certain programs may fight with the game client for control of your network drivers, or eat up so much bandwidth that the connection to the game servers may be slowed or disconnect. Bad data in your game or UI files can cause both connection problems and crashes. There are a lot of potential causes for this.
