As a frame of reference, I'm also with Century "NO" Link with 10mbps DSL, and pretty rural. Indeed, if I had ANY other viable choice, I would leave CL in a heartbeat, as their service is terrible. However, my latency is typically around the 30-40ms range when I am connected, so if you're getting ~300ms, then there is an issue somewhere. Given my history with them, most likely the problem is on their end. My neighbor is with them also, and also has the 10mbps package, and we will both simply lose connection at random times throughout the day, almost every day. I've had their techs out many times over the years, and the problem still exists. In fact, just this last Friday it was down for more than 4 hours. Sometimes it's 4 seconds, sometimes 4 minutes... unfortunately, sometimes it's 4 hours too. I call every time there is a disconnect, yet they can't seem to find an answer. They're just awesome... or not. Switch providers if you can!!!
