I wasn't referring to people who always have problems, and there may be other ISP's affected (also maybe you don't even realize you have Comcast as it operates under a number of names).

In our LS just tonight it was unplayable for people who had comcast, and those on Hawaiian Tel, Cox, and a number of other ISP's were just fine. Obviously it is not an issue with the server, but with whatever they are doing with certain ISP's based on feedback from the tech support thread.
