Ukrainian services dismantled the infrastructure of the main fiber-optic communication lines (FOCL) at the border crossings from Ukraine to the occupied Crimea. Thus, the Internet traffic from Ukraine to the Crimea no longer goes, but is sent through communication lines from the territory of Russia, writes the profile Russian edition of ComNews.

According to sources of the publication, the disconnection occurred on the side of Ukraine, at the initiative of the Security Service, and was a complete surprise for Ukrainian Internet providers.

Representatives of the telecommunications companies of the Crimea know only some details of this situation. The general director of Miranda-Media LLC Ivan Zima said that from the middle of July traffic from Ukraine to the Crimea does not go.

For today Crimea is connected with Russia by means of two FOCLs. In 2014, Miranda Media LLC built the first FOLS connecting the Crimea with the Russian Federation using the Crimean energy bridge along the bottom of the Kerch Strait. Its length is 46 km, its throughput is 8 Tbit / s. In early July 2017, Miranda Media launched a backup transmission line connecting Crimea with the mainland. The company built it using the electric power infrastructure on the site Simferopol - Rostov-on-Don. Its length is 905 km, its throughput is 4 Tbit / s.

"Such a trip happened, but, as far as we know, not at border crossings. I suppose that the SBU officers conducted an audit at the switching centers in Kiev and, possibly, in other cities where the communication lines passing through the Crimea were connected and unbundled, "said Evstar MT (SevStar), the general director of the Internet provider of Sevastopol, Konstantin Kokush.

He stressed that he can not officially confirm the dismantling or re-assembly. However, he officially confirmed that the transit communication lines that passed through the territory of Ukraine ceased to function. This, according to Kokush, was expected. And since the two communication channels of Crimea with the Russian Federation are working properly, the Crimeans did not notice any interruption in the provision of communication services.

Nevertheless, the consequences of dismantling may affect the cost of communication services on the peninsula. As Kokush noted, it is likely that this will result in an increase in the cost of communication services for the end user.
