Not available anywhere I've lived (Bay area, Chicago, SF). In fact I've only heard about it from Wikipedia. Never heard of anyone who knows anyone who claims to have even seen this in person.

It's not quite 100, but I get 75 Mbps on VDSL in Dallas.

If someone’s selling a non-symmetric ‘fibre’ service <= 100Mbit/sec, it’s probably VDSL2.

Downvoter... Care to elaborate? VDSL2 does very often get speeds of over 100 Mbps. It is a fact and a well known one.
