There is no false advertising from comcast, they have 100 Mbps speed available if you are willing to pay for it, otherwise you buy a lower tier of speed. If you are getting 1.5 Megabytes per second, then you got their 12Mbps speed. I have their 20Mbps speed and download at 2.5 MB/s from steam. I also always get my full speed 100% of the time from comcast. Even if Steam is being slow, I can still get the remainder of my speed downloading other things to get me to my 2.5 MB/s.
Anyways, when you got smaller countries with the land size nearly the same as a State in the US, it is easier to create an infrastructure for it, as compared to creating an infrastructure for the whole US.
