Just recently over the past few months my friends on telecom broadband have found that when they go over their cap and telecom reduces their speed to dialup, that when they download something or view a website the connection stops(not disconnected) and starts regularly.
 They said for example when they load seek.co.nz when their broadband speed is not slowed it loads continuously, but when their speed is reduced to dialup it loads(you can see router lights flashing and view packets sent/received) for about 5 seconds, then it stops loading, and 5 seconds later it starts loading again, and so on.
 I know dialup speeds are slower than broadband but i used to have dialup and even though sites loaded slowly, they still loaded continously, it didn't start and stop and start and stop.
 Are telecom not only slowing broadband speeds when the cap is reached, but doing something else to make this sort of thing happen?
