I have some AT&T MPLS sites under a managed contract with latency averaging 75-85 ms without any load. These sites are only 45 minutes away.
I've noticed this with AT&T's MPLS product when dealing with the internal corporate network here. I don't know what they're doing wrong but it is so very wrong.
circa 2007, noticed same thing: never below 90ms coast-to-coast across as13979. atm ds3 handoffs on both ends.
What is considered normal/acceptable?
Less than 10ms unless you're using a sub-T1 interface or going a very long distance.
