Russian Data Centers Hit by Ukraine Strikes Cause Outages

Russia's aggressive actions against Ukrainian data centers have backfired, leading to widespread outages of its own digital services. Ukrainian drone strikes have taken down three major data centers owned by Russian tech company Yandex over a short period.

The attacks, which began in late September, also hit Ukraine's telecommunications infrastructure and temporarily disrupted internet and mobile phone service for around 100,000 households in the capital city Kyiv. This was part of a broader campaign involving long-range strikes on Ukraine's power grid, transportation hubs, and residential areas.

As Russia continues to pursue its "data center war strategy, some pro-Kremlin bloggers are sounding alarm bells about the potential consequences for Russia's digital economy. They warn that the country is not prepared to withstand retaliatory attacks from Ukraine, which has a more decentralized system in place.

These commentators point out that if Ukraine continues to disrupt Russia's centralized infrastructure through targeted strikes on its data centers and other key systems, it could lead to widespread disruptions of essential services for Russian citizens.

Ukraine's military has responded to Russia's cyberattacks by targeting key infrastructure, including data centers owned by Yandex, a Russian tech giant also known as Russia's Google.

The first Ukrainian drone strike hit a data center in the Sasovo region southeast of Moscow on October 8, affecting two supercomputers that house Yandex's AI model, YandexGPT. The facility is equipped with Nvidia A100 GPU chips and boasts significant computing power.

One of these supercomputers, Chervonenkis, has a performance rating of 29.42 petaflops and ranks at 101 on the Top 500 List, while its counterpart, Lyapunov, has a rating of 20.03 petaflops and ranks at 161.

A second data center in the Kaluga region southwest of Moscow was knocked out by Ukrainian drones on October 9, marking one of Russia's largest data centers with a maximum capacity of 63 megawatts.

Another Yandex facility in Vladimir, east of Moscow, was forced to suspend operations after being targeted by Ukrainian drones on October 11, according to BBC News. This site houses the third supercomputer, Galushkin, which has a computing performance rating of 20.64 petaflops and ranks at 134 on the Top 500 list.

The impact of Yandex's data center damage extends far beyond its own operations, causing disruptions to various essential services in Russia. Payment apps and digital banking services have reportedly experienced interruptions or outages, affecting users' ability to manage their finances online.

Additionally, popular e-commerce platforms and video streaming services have been affected by the data center damage, making it difficult for consumers to access these services. Ride-hailing and food delivery apps, as well as navigation and map services, are also experiencing disruptions, further exacerbating the issue.

Yandex's cloud computing service is another area that has been impacted, with several large Russian companies relying on this service for their operations. These companies include major grocery and fast-food chains, as well as a household appliance retailer, according to The Moscow Times.

The reliance of these companies on Yandex's cloud computing service highlights the extent to which Russia's digital ecosystem is intertwined with the company's infrastructure. This hyper-centralization has proven to be a significant weakness for Russia in times of conflict.

This centralized structure allows for a single point of vulnerability that can have far-reaching consequences, as seen in the case of Yandex's data center damage.

Russian companies are facing significant challenges in setting up backup infrastructure outside of Russia to ensure wartime resiliency. This is partly due to the Sovereign Internet Law" passed by the Russian parliament and signed into law by President Vladimir Putin in 2019.

The law has effectively restricted Russian companies from using foreign infrastructure, even in countries considered friendly. Meanwhile, sanctions imposed on "unfriendly" nations have blocked access to their IT resources. As a result, replicating Russian IT infrastructure in neighboring countries like Belarus or Kazakhstan is extremely difficult.

In contrast, Ukraine's digital ecosystem is more decentralized, comprising smaller data centers that are less vulnerable to targeted attacks. The country has also taken proactive steps to build backup infrastructure, including relocating some equipment and networks underground or outside the country.

To support Ukraine's efforts, Western tech giants like Microsoft and Amazon have provided free cloud services to help migrate critical government services to other parts of Europe. This has enabled many essential Ukrainian digital services to continue operating despite Russia's ongoing missile and drone attacks.

Amazon Web Services is hosting a significant amount of data from Ukrainian organizations, including over 60 government entities and the country's largest private energy company, DTEK.

Russian forces' cyberattacks on Ukraine's data centers have had an unintended consequence: a significant delay for Russia's own IT operations. According to an unnamed expert, Yandex may not be able to replace damaged equipment for up to six months.

A lengthy repair timeline is also evident in Amazon Web Services' experience after Iranian drone strikes knocked out multiple data centers in Bahrain and the United Arab Emirates earlier this year. This incident highlights the vulnerability of critical infrastructure in the digital age, where a single attack can have far-reaching consequences.
