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...
