ELAN/EPLAN Latency

So we have several sites with Spectrum/Charter using their EPLAN product, basically any to any WAN product. Not that it necessarily matters, but it is VPLS/Bridge Domain on the back end from my understanding.

Our choice in using them is primarily based on the bulk of our branch office locations being in their service area, the most amount being the midwest.

We have a DR site in the Phoenix area, where they happen to have a POP at 120 E Van Buren. They were able to offer us a 5gbps circuit there, and it finally went live 2 weeks ago.

I started doing some testing and noticed latency around 103ms to 110ms, depending on which site on our ELAN i tested from. For some comparison, via internet/transit routes between these sites, we are in the 60ms-65ms range.

I started looking for comparison points, i check out he.net transpoort mapping tool, and it lists the path being at 35ms. I check the AT&T Latency POP tool and it lists 36ms.

I have been working with the NOC and my account team, and have not made any progress in 2 weeks. First the NOC blames the design ,which they send me. It is very inefficient, actually goes west to LA before heading back east (you would think it would go straight from PHX to Dallas like everyone else), which obviously adds on some latency. It does have a primary and backup path, but even mapping both routes, i cant come up with more than mid 60's ms. Given that it almost seems like some sort of configuration issue than a problem with the design itself. I have asked multiple times if anyone has taken the time to map the circuit as configured and test POP to POP latency to see if there are any discrepancies, and ive never gotten a clear answer if this has been done or not.

Certainly i am not in need of some super low latency route like im doing HFT or anything, and even the latency itself is not my largest concern, its where the hell this circuit is bouncing around their network for the end result to be this sort of latency, hell coast to coast isnt more than 70ms!

I have provided all of this information and they have not disputed anything and have not provided really anything for counter discussion. It really is pretty frustrating and disappointing. Obviously in hindsight i should have asked for the full design and expected latency upfront.

Has anyone had any experience with anything like this?
