  • The two arches are connected between Varna and Burgas and in the middle between Ruse and Kapitan Andreeevo.

  • There are also many smaller regional rings, each node in the network is connected by independent routes to the northern and the southern arc.

Connectivity in Bulgaria

As a major wholesale provider, Neterra serves about 50% of ISPs in Bulgaria. Neterra has built a physical (cable) connection with all first level providers (own international network or own data centers). Every Bulgarian ISP uses some of these first-level providers for its international connectivity. Thus, Neterra reaches directly 100% of the Internet traffic generated in Bulgaria, without transit steps on the road, even within the country. For greater reliability, Neterra's clients are connected to two routers, that serve the Bulgarian Internet space – main and back up.
