glbc just made itself a bit more global, expanding further eastward from its original European footprint. They have added new PoPs in data centers located in Sofia, Bulgaria; Bucharest, Romania, and Bratislava, Slovakia. Tenants in those facilities will now have easy access to the company's IP and data services. Driving the expansion is growing demand from the wholesale sector, including current customers from Eastern Europe that connect with the company in Vienna and Frankfurt who would like to do so from their own territory.
Today's new PoPs are powered by leased 10G wavelengths, though I'll bet dark fiber could be in the wings given sufficient demand of course. According to a company spokesman, they have already sold much of the initially deployed capacity into Bucharest - so the demand certainly seems to be robust. I wonder if the company has further PoPs in mind in the region, after all there's always Istanbul.
Eastern Europe has been a battleground for many carriers for the past few years, with Level 3, Interoute, and Cogent amongst others adding dark fiber and PoPs to their networks throughout the region. Global Crossing itself added IP PoPs in Budapest and Warsaw in 2009 prior to this expansion. All are drawn by the rapid growth of IP traffic in the region, which Telegeography recently pegged at above 100% (like that in Asia). Prices have fallen as competition has increased, but it remains a region full of opportunity in the wholesale market.
