Quote from GTS:
Its very likely that changing ISP's from cable to DSL will change the route since different ISP's connect to the internet backbones in different ways.
You could also do traceroutes from different places on the internet (http://www.traceroute.org/#USA) to see if there is any common problem but that would only be helpful if the problem was readily reproducible which doesnt sound like its the case.
the verizon guy said it was more reliable then cable and it didn't hop so many times, he said 20 was way too many hops
I quess i'll find out
Thanks for the help
and I came back with all good reads and under 85milliseconds, Denver to Chicago.
