Yandex said Monday that all three of its supercomputers remained unharmed following a series of Ukrainian drone attacks against its data centers and have been moved to more secure locations.

“Once brought back online, the computers will rejoin Yandex’s service infrastructure,” the Russian tech company said in a brief statement. “They will also continue to be used for training foundation language models.”

It marks Yandex’s first comments about the three supercomputers — called Chervonenkis, Galushkin and Lyapunov — since Ukraine began launching air attacks against the company’s sites earlier this month.

The supercomputers, launched between 2020 and 2021, rank among the most powerful in the world. But as the global AI race has accelerated in recent years, their position on the list has gradually slipped.

Ukraine’s attacks against Yandex data centers have led to temporary outages of the company’s services across Russia, including ride-hailing apps, food delivery platforms and banking. Corporate clients on Yandex Cloud have also been impacted.

The Kremlin has said that, while it is too early to assess the financial losses, Yandex was taking steps to deal with the aftermath of the attacks.

Russia’s Digital Development Ministry said it helped Yandex migrate core systems to external backup servers.

The ministry has also approved recommendations for protecting data centers against Ukrainian drone attacks, the Kommersant business daily reported Monday, citing the document.

The measures include building the most critical facilities underground, installing structures capable of withstanding blast waves, deploying electronic warfare systems and maintaining backup copies of data. They also call for regular coordination with the military and National Guard.

President Vladimir Putin vowed retribution for the attacks and earlier ordered officials to improve Russia’s ability to protect its digital infrastructure. Ukraine said it was responding to Russian attacks on its own data centers.
