Russian military strikes hit a data center in the Odesa area of Ukraine operated by local Internet service provider Tenet.

A bank’s data center and another hosting firm in southern Ukraine have also reportedly been hit this month, following numerous other strikes on Ukrainian facilities by Russian forces.

“As a result of a hostile attack, a blow was struck to the Tenet technological complex,” the company said in a post on October 10. “Significant damage was recorded to the facility's life support systems, in particular the cooling systems and power generation equipment.”

Tenet lists its location as 106 Bazarna Street in central Odessa. The company said the office is closed to visitors for part of this week due to ongoing technical work.

The Russian Ministry of Defense claimed Tenet’s facility was being used by the Armed Forces of Ukraine to process, transmit, and store information.

In a series of updates over the weekend, Tenet said there is no fixed schedule for repairs, but repair work may cause temporary local interruptions in network access in certain locations. The company noted, however, that its total network capacity is “stable.”

Tenet is a telecoms company founded in Odessa in 1992. The company offers Internet, TV, and telephony services in the region. It also offers domain, web hosting, and colocation services from its own data center.

According to local press, government administration buildings were also damaged as part of recent Russian attacks on Odessa over the weekend. There were reportedly no deaths.

This weekend also reportedly saw Russian forces strike a Ukrsibbank data center in Kyiv. Again, the Russian military said the site was being used by the Ukrainian military. The BNP Paribas-owned bank is yet to comment.

The RX-Name data center in the Nikolaev/Mykolaiv area of southern Ukraine was also reportedly hit by Russian attacks last week. RX-Name was founded in 2002, offering web hosting. Its data center dates back to 2005.

Multiple Ukrainian facilities have been hit in recent weeks, including facilities operated by Parkovyi Data Center, MiroHost, Datagroup, Vodafone Ukraine, De Novo, Cosmonova, Omega Telecom, and Ukrtelecom.

Russian data centers have been hit in turn by Ukrainian drones. Yandex, one of Russia’s largest technology firms, has seen three of its five facilities hit by Ukrainian strikes in the last week. The company’s Vladimir data center near Moscow was hit over the weekend; its facility in Sasovo was struck on Thursday and its Kaluga facility on Friday.

Earlier this year, Ukrainian forces struck a data center in Russian-occupied Ukraine in Prymorsk.
