Dzhubga, Russia

How the Internet Reaches Dzhubga

Dzhubga is a coastal settlement in Russia, situated on the northeastern shore of the Black Sea in the Krasnodar region. Its position on the Black Sea coast places it within reach of submarine cable infrastructure, and international internet traffic arrives at Dzhubga through a single submarine cable landing directly at this point. Rather than routing through a distant inland hub, Dzhubga functions as a direct cable terminus on Russian soil.

That single cable — the Georgia-Russia cable — connects Dzhubga to the country of Georgia across the Black Sea. All international submarine traffic arriving at Dzhubga travels this route, making the Georgia-Russia cable the sole undersea link serving this landing point.

The Cable Serving Dzhubga

The Georgia-Russia cable spans 433 km and has been in service since 2000, making it the earliest submarine cable to land in Russia. It links Dzhubga to Poti, Georgia, connecting Russia and Georgia beneath the Black Sea. A second Russian landing point on this cable is Sochi, meaning the cable effectively serves two Russian coastal cities alongside its Georgian terminus. The route is regional in character, crossing the Black Sea rather than spanning an ocean, and it facilitates connectivity between Russia and Georgia along a relatively short but strategically positioned corridor.

Regional Context

Russia hosts 12 submarine cables across 24 landing points, with an average cable length of approximately 5,002 km. Dzhubga is among the smaller terminuses in this national picture, served by a single cable compared to other Russian landing points such as Anadyr, Ilyich, Nakhodka, Petropavlovsk-Kamchatsky, and Sovetskaya Gavan, each of which hosts two cables. Dzhubga's neighbor on the Georgia-Russia cable, Sochi, lies along the same stretch of Black Sea coastline and shares the same cable infrastructure.

What This Means for Connectivity

Because Dzhubga is served by a single submarine cable, all international submarine traffic at this landing point flows through the Georgia-Russia cable. An outage on this cable would sever the undersea link between Dzhubga and Georgia entirely, leaving no alternative submarine route at this terminus. The cable's destinations are regional: packets travel across the Black Sea to Georgia, making this a corridor for connectivity between these two neighboring countries rather than an intercontinental route.

Understanding Dzhubga's position — a single-cable Black Sea terminus shared with Sochi on the Russian side — illustrates how submarine cable coverage within Russia varies considerably by location, with some points deeply integrated into multi-cable networks and others, like Dzhubga, dependent on a solitary regional link established at the very dawn of Russia's submarine cable era.
