I've had difficulties reaching anyone with a brain
at my DSL provider Verizon California.

I can reliably ping the first hop from my home to
the CO with a 25ms delay. But if I ping any other
location, packets get dropped or significantly
delayed. To me, this sounds like Verizon has an
internal routing problem rather than a problem
with my phone line. Note that it rained recently
in our area and the cable vault in front of my
is usually covered with stagnant water because
the gutters don't drain it away.

I have tried to explain this to tech support but
they refuse to go off script, even the supervisors.
They keep insisting on sending a tech to my home
when I suggest this should be escalated to their
network operations team.

Anyhow, if I can reliably ping the first hop
from my home, would that eliminate my telephone
connection as part of the problem? Just a sanity
check on my part. Thanks.

Is your DSL modem of the type that you can log into and check the line
stats?

Even if there are phone line problems, you still have sync, and
regardless what the sync rate, line noise etc are, if you can ping
across the link and get a reply, replies should come back from distant
gear as well.

Perhaps an op from another relatively local provider could supply you
with a temporary DSL auth account to see if that will route you around
the problem.

I could supply you one, but I'm in southern Ontario, Canada, so I don't
know if the realm would properly route all the way back here or not.
