Equinix is the most popular with TelX bringing up second place. Both have expensive cross connects. There are others, but they aren't relevant for interconnection. Intra-building connectivity is damn expensive. https://peeringdb.com/advanced_search?address1__contains=350&city=Chicago&reftag=fac ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Jason Lixfeld" <jason+nanog@lixfeld.ca> To: "NANOG mailing list" <nanog@nanog.org> Sent: Thursday, November 22, 2018 2:09:08 PM Subject: 350 E Cermak Hey all, Looking for some clue on how things work, and who’s who for colo at 350 E Cermak. Looking at possibly putting a rack in somewhere there for a Peering/Transit/PNI POP. Is there a list somewhere of colo facilities in that building? Also, how does it work there in terms if inter-colo, intra-building connectivity, or is that a mixed bag? Thanks!
