The PTT is limited in 50 megs in this building. However, the cable company just upgraded its network and is now 
offering up to 500. I assume the cable company is using coax and may be that gives them an edge when combined with VDSL 
to get up to 500 megs.

DSL on the whole seems pretty unpopular in the USA. VDSL itself is a fairly old standard but it's been enhanced over 
the years to provide bandwidths up to 300mbit on a single twisted copper pair, albeit over relatively short distances.

DSL (these days, specifically VDSL2) is extremely popular and widely used within the UK because almost every home has a 
single twisted pair going into it for a POTS phone line. It made sense to run services over this than to re-cable 25 
million homes. A (very) slow FTTH rollout is under way but what seems to be getting more traction is a rollout of 
G.Fast which currently boasts speeds of up to 500mbit over short distances (< 100m), still on a single twisted copper 
pair. This may be what you're getting as VDSL2 won't push to 500mbit over any sensible distance.

I can only speculate on why they decided to use DSL in your building - if it has legacy POTS infrastructure to each 
apartment, it would make some sense. If not, who knows...
