Carrier Ethernet Exchange protagonist CENX (news) and Zayo's zColo division have signed an agreement under which CENX will deploy its platform at the critical 60 Hudson Street datacenter in New York City. It's one of the most-connected buildings in the world, and will give CENX easy access to hundreds of operators of all stripes.
zColo of course derives mostly from Zayo's Fibernet Telecom Group acquisition in the summer of 2009, and the Meet Me Room at 60 Hudson and other infrastructure there had always been FTGX's premier assets. With Google's tentacles apparently expanding within the other giant NYC interconnection facility at 111 8th at the expense of other tenants, 60 Hudson and its Meet Me Room seem poised to gain further influence and it's easy to see why being in that facility might attract CENX.
Thus far Zayo itself has not seemed interested in the Ethernet Exchange business, choosing to focus all its efforts at the infrastructure level. But their datacenter and interconnection division obviously is happy to have such a tenant, and the customer relationships that might derive from hosting an Ethernet Exchange certainly can't hurt Zayo's overall efforts to expand its customer base.
CENX has been relatively quiet lately, and seems to have been spending some effort tuning their operations internally as the whole Ethernet Exchange business continues to evolve toward something that actually (hopefully) makes real money. Between Equinix, CENX, Telx, and Tinet/Neutral Tandem, we have four rather different approaches to the whole idea still in play, and soon we should have a better idea of what works and what doesn't.
