Ruse sits on the Danube directly opposite Romania, and Neterra's data centre there - 16 Carkovna Nezavisimost Street, floor 17, Ruse 7004 - is built around that geography. Fibre across the river reaches Romanian ISPs, and the building is the principal point of presence for the Black Sea Fibre Optic Ring, the shortest optical route between Romania and Turkey. Six networks take service in it and two exchanges open onto the floor, Balcan-IX and NetIX, both associated with Neterra; BIX.BG, the Sofia exchange, is not among them. For a room drawing on the order of 130 kW that is a lot of interconnection. The Sofia Data Center name is a brand, not a company: Neterra Ltd. sells under it at four addresses - SDC 1, SDC 2, SDC Stolnik and this one, some 300 km east of the capital - so a contract here is with Neterra.
Sofia Data Center is Neterra's brand name rather than a location. It covers four facilities - SDC 1, SDC 2, SDC Stolnik and SDC Ruse - and Ruse is roughly 300 km from the capital.
Which internet exchanges reach the Ruse floor?
Balcan-IX and NetIX, both Neterra-associated. Six networks and one carrier take service in the building.
What makes the Ruse site useful for cross-border traffic?
Fibre across the Danube connects it to Romanian ISPs, and it acts as the main point of presence for the Black Sea Fibre Optic Ring between Romania and Turkey.
Which company does a tenant actually contract with?
Neterra Ltd., the Bulgarian operator that trades under the Sofia Data Center brand.
What compliance does the SDC estate claim?
ISO and PCI DSS certification, stated across the group rather than per building. No Uptime Institute award is registered for any Neterra site.
