Have you tried contacting them? We were there a few years back and it took a pretty large commitment with Equinix in general (space in most of their facilities and peering fabrics) for them to find 1/2 cabinet with 20A.
I'm not sure what the availability is like today though.
This place is full. Haven't seen any opening for a while.
Internap had 3 racks available 4 months ago that I almost jumped on (I even told you about it).. They have a small bit of churn in their PNAP so sometimes they can get space... Plus, Internap's support is just awesome. [email protected] is probably the most useful e-mail support i've ever dealt with. Certainly blows 365main out of the water.
