I got that same response from Cogent in August and October when we complain=
ed (word for word).  Sometimes it's bad, sometimes it's "ok".
Happens with Comcast sometimes too, but the peer to Verizon is usually wors=
e.  I can show packet loss with an MTR anytime of day.  Today is an "ok" da=
y....  just 5% loss on average.
