The carrier corridor between Middle East, Caucasus and Europe.

We started Sofia Connect because the carriers serving Southeast Europe were optimized for east-west European transit, not for the corridor that actually matters to Bulgaria: Dubai, Yerevan, Tbilisi, Istanbul and Frankfurt.

Since then we have built our own fiber and DWDM network in Bulgaria: the core in Sofia and Sofia Connect Edge facilities in Plovdiv, Stara Zagora, Burgas, Montana, Pleven and Blagoevgrad. Together with partners we serve 11 more points: Varna, Dobrich and Balchik in Bulgaria, and Frankfurt, London, Istanbul, Athens, Tbilisi, Yerevan, Agarak and Dubai.

Through a partner we also provide capacity on the Caucasus Cable System between Balchik and Poti, which connects Europe to the Caucasus across the Black Sea without transiting Türkiye. For carriers that need a path between the EU and the Caucasus that does not rely on Istanbul, it is a direct alternative.

Everything we sell — IP transit, Ethernet / L2VPN, DWDM wavelengths and dark fiber (Sofia metro today, with national and cross-border corridors on the roadmap) — is delivered on the same AS47872 core with a single 24 / 7 NOC. One AS, one SLA, one NOC.
