Most Provider type datacenters I've worked with get a lot of flak from

there's always going to be a certain amount of chance (at least) of

I think the big push to get the fcc to define broadband is highly based
on the rus/ntia setting definitions of what broadband is. If any anyone

The trouble with broadband in rural America is the twisted pair loop lengths
that average around 20,000 feet. To use VDSL, the loop length needs to down
around 3000, so they're stuck with ADSL unless the ILEC wants to install a
lot of repeaters. And VDSL is the enabler of triple play over twisted

As tedious as the downstream can be, engineering the upstream path of a cable

A lot of older systems were never designed for upstream service. Even if the
