My local ISP trenched fiber to my house for free and provides gig internet for $80/month.
The funny thing is my previous house was in town and I had to settle for 100Mbit for the same price. ISPs are all sorts of messed up.
In the city it’s often just as easy to let what is working continue “working” - a major rollout takes a lot of money.
(I'm on Comcast's Business service, $250/mo for 1000/35 [long dumb story why]. Most of the time I see under 600 down when checking on speed test sites, and real-world speeds downloading large files rarely exceeds 250. I expect real-world speeds on the non-business service are even worse.)
It's pretty embarrassing that this is the state of things.
Over in Oakland I am paying $40/mo to Sonic for 10Gbps (though I only have equipment to route at 1Gbps at the moment)
There's a benchmark posted there showing that the speed is really as advertised.
