Sorry, no. MUCH closer. All are under 125 miles from headquarters.

No fiber, all full T1's at each site. I just averaged 28ms - 31ms between me and all other 8 sites. My provider's SLA states 50ms or better. From: Stringham, Steven [mailto:[email protected]] Sent: Thursday, May 05, 2011 2:14 PM To: NT System Admin Issues Subject: OT: MPLS Latency We have a few sites on our MPLS network with Twtelecom. Some of the have pretty good latency (<10ms for Phoenix to Las Vegas - all fiber to the building) to not so good latency (40ms Phoenix ->Reno Nevada - Dual T1s in Reno). I am seeing similar latency (38ms) from Phoenix to San Jose (another dual T1 on the San Jose side, but a fiber connection to my Phoenix side. My Phoenix to Albuquerue (all fiber again) is about 15ms. This is about the same distance as to the San Jose - but over double the latency. Strict math (best case - line of site 2/3 speed of light calculations) say that my Reno line should be about 10ms. So, I double it for equipment and I still get 20ms. Less than half. My question is what do you folks see out there? Do you see a higher latency on a T1 line than a fiber to the building line by that much of a difference? Or, is there a routing issue that is creating delays? Any feed back you can give would be helpful.
