Wow the US really has it bad when it comes to home internet. In many European countries, you can get symmetric Gbit internet for 30-40 EUR (probably less in some places), and I haven't seen a data cap in forever.
I have had a fibre cable poking out of the footpath in front of my apartment for a year or two now, waiting for ODF or whoever to come and install it into the building.
IIRC, Init7 explained that basically the internet wants to be fast, but ISPs want to spend lots of money on special equipment to slow down your internet so that they can sell speed tiers and data caps.
The US is much more captured that Switzerland, of course. Providers in the US get billions of dollars to expand their networks and provide service, and then don't provide the service, and nothing happens.
And my drives aren't fast enough for 25.
My parents live in a small, countryside village. They have fiber at the same prices (including 4Gbit symmetric, though they are happy with a cheap 200Mbit subscription).
And FWIW, I own my house in the east bay — I am the landlady ;)
I'm aware. And it's my understanding that -sadly- much of the Google "Fiber" deployment in the area is a WISP, just like Monkeybrains is. Quite a while back, Google Fiber bought Webpass and continued doing WISP deployment in the SFBA under the Google Fiber brand. (Because it's politically dreadfully hard to run fiber optic cables in the area.)
If you haven't contacted Monkeybrains for a minimum and expected speed quote at your site in a year or five, it's worth doing it again. It's my understanding that they aperiodically upgrade the hardware in their core network as well as the sort of hardware that they deploy at customer sites.
Monkeybrains' down-to 100/100 service is -on paper- far, far slower than the up-to 1400/40 service I was getting from Comcast, but the actual, delivered speed that I'm seeing from Monkeybrains varies between 300mbit and ~1000mbit (sustained) depending on what other folks are doing on their network. [0] I'm in a fifty-apartment building, so it's possible that they've installed faster gear on my roof than they install in smaller (or single-family) buildings. Reports on the Internet seem to be somewhat mixed, with some single-family buildings reporting ~1gbit service, and others reporting ~45mbit.
[0] Typical prime-time speed is something like 400mbit. Off-hours speed is frequently very close to 1gbit. The only time I've seen the minimum speed was when I had a poorly-crimped Ethernet cable between my router and the rest of my LAN that would intermittently only link up at 100mbit.
