In Blacksburg, CNS has redundant fiber uplinks from the [[Andrews Information Systems Building]] to Ashburn, Virginia and Atlanta, Georgia. The [[Mid-Atlantic Broadband Communities Corporation]] provides the dual OC-192 (10 Gigabit) connections to Ashburn and either OC-192 or OC-768 connections the additional connection (possibly two?) to Atlanta.
CNS's primary upstream routers are located in Equinix's [[Ashburn, Virginia]] datacenter. At Equinix, CNS has about 4 Gbps aggregate bandwidth for commodity Internet from Cogent, as well as, through the [[Mid Atlantic Terascale Partnership]], connections to [[Network Virginia]], [[National LambdaRail]], and [[Internet2]]. They are also a member of the [[Mid-Atlantic Research Infrastructure Alliance]], although it is unclear what role this alliance provides in providing connectivity.
