Yea I have to agree, these speed issue threads I think are more related to local issues at the CO then with a more wide spread issue. While I do not have a latency monitor setup right now I have not had any problems with speed both from inside and outside the US. In my case I have the 150/65 plan and I get near that every time with the exception of the last one in California.
