Latency in ATT DSL from Houston.

Thu Mar 17 17:02:00 UTC 2016

Hello All,

    I am trying to get some assistance with latency I am seeing inside
ATT. DSL Support has been next to useless, and I am already pursing
different connectivity options, but getting this fixed would be
awesome. The problem is two fold, I see latency to pretty much any
destination, that starts after my modem / gateway. The second part of
the problem is mostly clerical, ATT seems to be using IANA
documentation space inside their network, which DSL support has no
explanation for.

    If someone from ATT could reach out to me off-list, that would be
greatly appreciated.
