The international carrier arm of Swedish telecommunications giant Teliasonera is opening a new node in the southwest at i/o Data Center's Phoenix One facility. Teliasonera has been relatively quiet in North America for a long time, selling wholesale bandwidth out of the top ten or so markets but not much else. They don't need Phoenix for that business, but rather they seem to be actively trying to more effectively reach national and multinational corporate clients and are moving beyond. That shift in focus suggests that further expansion markets may be in the offing - Denver and Seattle perhaps?
It is easy to forget that Teliasonera is perhaps the only European PTT that still maintains an actual fiber backbone in the US that it picked up via swaps back in the bubble from Wiltel. Last year though they upgraded it with Infinera gear which suggested expansion might be on the way. If I'm not mistaken, that Viking fiber network passes through Phoenix and I have been told that their new PoP at i/o is indeed fed by their own fiber rather than some leased waves.
For its part, i/o Data Centers' Phoenix One datacenter just opened last summer and has been gaining traction at an impressive rate with a dozen carriers now serving customers there. Part of their success has been excellent timing - Phoenix has become a hot market across the board and they have a nice new, huge facility with space to sell. But another part is the fact that they do not charge for cross connects, which makes them attractive to carriers looking for interconnections in the region. Adding Teliasonera as a carrier gives their carrier connectivity a substantial international boost.
