> Google Fiber isn't rolled out to most of the bay area.

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.
