It was decided to locate Concerts global HQ in North America, the largest global telecommunications market. Reston, Virginia was chosen as it was both easily accessible from Europe, and sat in the then developing telecommunications and technology corridor of Northern Virginia. Concert started building its Global network in 1993; unlike its competitors FLAG and COLT who physically built their network using their own assets, Concert grew rapidly by purchasing capacity from other TelCo's.
