A drone attack overnight on 8 October caused a fire that hit part of Yandex's data center in Sasovo, Ryazan Oblast, about 580 km from Ukraine, and the site is fully stopped, the Russian tech company told Russian media. The data center sits on the grounds of Sasta, a sanctioned machine-tool plant, Russian outlet Astra said, citing Wikimapia data. Astra's OSINT analyst found from eyewitness footage that the fire hit the plant.

Since late September, Russia has been striking data centers in Kyiv that keep Ukraine's internet and online services running. Now a drone attack has stopped one of the data centers that Russia's largest tech company relies on.

Yandex counts the damage

Yandex warned that some services may be unavailable, while its core services kept running and no one was hurt. Ryazan Oblast Governor Pavel Malkov claimed two drones were downed, a roof caught fire at an enterprise in the Sasovo district, and windows were blown out in several homes.

The power failure took down a wide range of Yandex Cloud infrastructure, including computing capacity, networks, data storage, databases, Kubernetes, cloud services, AI, and security and monitoring systems, Ukrainian outlet ZN.ua reported, citing Exilenova+.

Ukrainian monitoring channel Exilenova+ reported that the plant was hit, without naming an attacker. The channel said Sasta, which claims a place on Russia's register of defense-industry companies, makes computer-controlled machine tools, including five-axis machining centers, and previously supplied the Tactical Missiles Corporation (KTRV) and Roscosmos. The plant's value to the arms industry lies in machines that cut precision parts, not in finished weapons, the channel said.

Citing Exilenova+, Militarnyi reported that Ukraine's Defense Forces hit the plant. It also linked Sasta to Iskander missile supply chains. No source has said whether the plant or the data center was the target, and no Ukrainian official has claimed the Sasovo strike. Sasta has been under US sanctions since November 2023, UK sanctions since February 2024, and Ukrainian sanctions since April 2025, a sanctions database shows.

Salavat: Kyiv reports a hit

Ukrainian forces hit the Gazprom Neftekhim Salavat complex in Bashkortostan, about 1,380 km from the front line, causing a fire, Ukraine's General Staff said. It said the complex processes up to 10 million metric tons of hydrocarbons a year and serves Russia's armed forces. Its key unit, the ELOU-AVT-6 primary oil refining unit launched in 2012, can process 6 million metric tons a year, Militarnyi reported. Astra's analyst placed the fire a few kilometers outside Salavat, possibly near the refinery.

Salavat Mayor Marat Zagidullin claimed that debris from several drones fell in the industrial zone that morning and started a fire.

"The enterprise continues to work," he said.

Astra noted earlier hits on the complex on 24 September 2025, on 14 July 2026, when refining fully stopped, and on 13 August 2026.

Russia's strikes on Ukraine's data centers

Russia has repeatedly hit data centers in Kyiv since 23 September. Strikes hit the COSMONOVA data center twice, the second time knocking it out, and the Parkovyi data center stopped working completely on 1 October after a series of strikes. In early October, Russia destroyed the dline.ua data center in Kyiv.

A company of unmanned ground systems from Ukraine's 92nd Assault Brigade used the robotic system Frodo to evacuate a wounded soldier, Frontline Robotics told Militarnyi on 7 October.

Ground robots are being used to evacuate wounded soldiers from the drone-dominated "kill zone," a band tens of kilometers deep on both sides of the front line. About 112,000 logistics and evacuation missions by ground robotic systems were recorded from January through August 2026, according to Ukraine's Defense Ministry.

Operator credits speed and suspension

The operator, callsign Tango, named speed and the ability to perform complex maneuvers as the robot's main advantages, according to Militarnyi. The unit also praised Frodo's adaptive suspension, which it said smoothed out rough terrain and kept the wounded soldier's transport relatively comfortable.

What Frodo can carry, and how far

The robot has a 6×6 wheel layout with independent suspension, adjustable ground clearance of 170–330 mm, and a top speed of 40 km/h. Its recommended payload is 200 kg, and its maximum is 400 kg, according to Frontline Robotics. The company lists its range as 150 km on asphalt and up to 90 km over rough terrain with the recommended load. Frodo supports several communication channels, and one person can swap its batteries in about two minutes.

Frodo had passed the Defense Ministry's codification and could carry remote-controlled modules such as the Burya turret, Militarnyi reported on 30 September.

The 92nd Brigade had used ground robots to evacuate wounded soldiers before. In September 2025, the brigade evacuated three wounded soldiers using a ground robot, according to Militarnyi.

Russia has shown a drone interceptor built on the Alazan, a civilian anti-hail rocket, Militarnyi reported. The sample went on display at a weapons exhibition that Russian dictator Vladimir Putin toured at the Chebarkul training range in the Urals on 2 October.

Ukraine now sends drones at Russia by the hundreds, by Moscow's own count. Russia's Defense Ministry claimed its air defenses intercepted nearly 900 overnight into 6 October. Russia's missile-based air defense was built to repel aircraft raids and a few cruise missiles, not swarms of low-flying drones.

In May, Ukrainian intelligence said Russia was adding four regiments, 24 battalions, and 162 batteries to counter Ukrainian strike drones. The converted Alazan, which Militarnyi calls an anti-drone system, is one more piece of that search. Meanwhile, the commander of Ukraine's Unmanned Systems Forces, Robert Brovdi, said his forces struck 300 Russian air-defense assets between January and 19 September.

From hail reagent to shrapnel

Based on the size of the sample on display, the interceptor builds on the Alazan-2M or Alazan-6 series, Militarnyi assessed. The outlet put the stated cost at up to $12,000 per unit but did not say who named the figure. In civilian service, the rocket flies about 10 km, climbs up to 8 km, and carries about 0.5 kg of reagent. For air defense, the developers plan to replace that reagent with a fragmentation warhead.

Militarnyi's analysis of the published photos describes the front end as a steering assembly: four cruciform deflector fins, probably paired with a seeker or a fuze. At the rear sit folding stabilizers and the open nozzle of a solid-fuel motor, held in a metal cradle.

One sample among 300 exhibits

The Kremlin's account of the visit lists more than 300 weapons on display, including interceptor drones, but does not mention the rocket. Propaganda channel Russia 1 aired the interceptor in its report from the visit, and the Kremlin pool of state news agency RIA posted photos.
