RE: T3 Latency

["Aaron Moreau-Cook" <aaronm () toothpick net>]

I know one of my circuits runs from Seattle to Los Angeles to El Paso (fiber
cut a few weeks ago) to Washington DC and finally to New York City.

Nice to know my packets get to visit almost 15 states before hitting their
destination.

Wayne:
  Now there's a thought that didn't occur to me. They may be running me
all over creation for some reason rather than taking some more direct
route. Perhaps they ran out of somthing here in Michigan and had to run it
down to Texas and back to get it connected correctly. I think I'll have
them inventory the path and let me know what it is.

Thanks to all the responses on this.
