Somehow some random telcos have found a way (presumably government subsidies (I don't think that is bad)) to provide some amazing service, while others wallow in absolute trashy telco service.
I know folks with consistently low latency 1Gb service that is just amazing, and folks where the local telco literally left lines lying across their lawn providing terrible service claiming they'd get back to it and never did.
I worked with one rural telco provider who had datacenter grade switches running 1G sfps (they could have run 10G sfps on all of the ports if they chose to do so) ... one port per household. I talked to the guy running the show there for a while and he said they just had this massive budget so "why not?". He noted almost none of the houses used their service to its fullest extent with the exception of some local teens ;)
