As much as I want to love Monkeybrains.. 20mbps for $35 is way more expensive than Comcast, and their weird coverage map is unclear where you can actually get it. I tried to contact their customer support and didn't manage to get a reply. At least comcast tells you you're getting screwed, and doesn't ghost you.
Sorry you didn't get a reply. We respond to every inquiry, but sometimes the responses end up in one's spam folder. We run our own mail servers and despite our best efforts (DKIM, SPF, never being on any blacklists) some mail providers bin us.
If you give us a call (415-974-1313) we can look up your address and give you a better idea of what to expect, though we tend to under-promise and over-deliver.
The website is a bit... dated, but we're working on a new one with a new coverage map[0] and more details about our service in buildings that are already on-net.
I'm in Duboce Triangle and get the same 65Mbps up and down. There have only been two short outages since I got the service two months ago. Given I'm paying a third of Comcast's price, I can stand 30 minutes of no internet.
