That building is mostly vacant. All their switchgear takes up very little space compared to what it must have been in the Long Lines heyday.

They have some suites in there. An employer I had ages ago had an 15454 in there because we picked up an OC-12 there. One rack in a room that easily could have held a dozen.

It’s not marketed or advertised, obviously. The CC Pop at 474 is really all there is in the city. There are a few carriers there, but all the serious stuff is in Markley Boston.
