I am in San Francisco, CA currently. Thought I may continue my datacenter tour (visited Colo4Dallas and RackShack in Texas last week). Any nice colo providers here worth checking? ;)

I know colo.fm uses it as do others.

Savvis has one, and I think efreeservers is in a Level3 datacenter.

Efree uses www.exchangecolo.com from what I know.

Interesting colo.fm's address is the same as eXchange colo: 200 Paul Avenue. So it must be the same facility ;) Anyway, hope to visit them today.

Isn't Huricane Electric in Freemont?

Cogent doesn't have any facilities at all.

Colo.fm, efreeservers and also 321Host-It :) are at 200 Paul Ave which is owned by eXchange Colocation. It is one of the greatest data-centers in northern California and definitely worth being checked out.

Then what do they have? How can they offer 100Mbps for $1000?

Cogent has a presence in the biggest data-centers across the country, most of which are carrier neutral.
Cogent just 'lights up' a given data-center (provided it's big and good enough for them) by bringing in a fiber line to their backbone. Then they install their equipment in this data-center and when anyone wants connectivity from them, the data-center staff establishes a cross connect from Cogent's switch/router to the customer's location at the data-center. After doing this, the customer can use their Cogent pipe. This is a highly cost-effective way to sell bandwidth.

Cogent does not run any facilities (data-centers) on their own.
