Re: Verizon Policy Statement on Net Neutrality

Daniel,

We'd have to come to some standard definition of, "But even if 1% of users
would reasonably be using a fully symmetric link to its potential..."

As I said, I have visibility into a large number of symmetric connections
and without exception they'd fit well into a plan that offered upstreams
with that had a fractional speed of the downstream.  Now, keep in mind I'm
not talking about 1/10 as a ratio here, but 1/5 would accommodate ~99.2%
and 1/4 would fit ~99.9%.  It's also important to note that all of these
accounts are in the >25mbps down territory so their upstreams are >5mbps.

What I see when I look at customer satisfaction ratings is a very strong
correlation with low uplink speeds and a high satisfaction rate when we
look at uplink speeds greater than 4mbps.  What I don't see is an increase
in customer satisfaction as upload speeds go past ~6mbps.  Conversely,
increases in customer satisfaction with correlate with increases in
download speeds past ~30mbps before the correlation starts weakening.
