The over-subscription was definitely a problem. The ISP I worked for had a fractional T1 in their main POP for frame relay (512K or something?) There was about 4 to 5x in bandwidth needed for customer connections, assuming 100% utilization. During peak times in the evening, the FR was massively overloaded and ping times would get into the 100's of milliseconds (normally it was 10 to 15ms IIRC.) The connection never went down though, even when they were slow.
