Russia struck a Kyiv data centre twice on the morning of September 27, injuring three people including two children, Zelenskiy said, widening its campaign against Ukraine's communications.

Zelenskiy said on September 26 that Russia is waging a campaign against Ukrainian data centres, infrastructure and communications to leave Ukrainians without internet access, communications and digital services, the Kyiv Independent reported. Russia's defence ministry said it hit a Vodafone data centre in Kyiv overnight; Vodafone Ukraine had not commented.

Russian attacks killed 14 people and injured 57 across Ukraine over the past day, with the Odesa region hit by what its governor called a "mass strike", the Kyiv Independent reported on September 27.

Ukraine's defence ministry said its forces struck six strategic Russian refineries in one week, up to 1,600 km behind the front line. Satellite imagery published by Radio Svoboda showed three of the Ilsky refinery's six primary processing units damaged, according to the monitoring account NOELreports.

Refinery strikes

Krasnodar region: Radio Svoboda satellite imagery indicates the September 26 strike on the Ilsky refinery damaged three of its six primary processing units, AT-4, AT-5 and AT-6, which together provide 99% of its primary refining capacity, as well as the tank farm, and that production has stopped, according to the monitoring account NOELreports. Militarnyi separately reported satellite imagery showing damaged tanks, pipe racks and a crude distillation unit. Fire Point, which makes the FP-1 drone, had said the strike forced the refinery to halt, the Kyiv Independent reported. No industry source has confirmed a halt.

Krasnodar region: the operational headquarters of Governor Veniamin Kondratyev said the night attack of September 25 to 26 on the Seversky district killed three people and injured two, one critically, left about 26,000 residents without power and cut railway power lines before train services were restored, Fontanka reported. Russian officials have not named the Ilsky refinery. Fire Point, which makes the FP-1 drone, said the strike damaged three primary oil-processing units and a tank farm and forced the refinery to halt, the Kyiv Independent reported. Ukraine's General Staff had confirmed the strike on September 26.

Perm: new satellite imagery of the September 25 strike on Lukoil's Perm refinery shows hits on a building identified as TIT-310 and on process racks near the AVT-5 unit, with possible fire traces around the AVT-4 primary unit, according to NOELreports. The refinery halted crude processing after the strike, industry sources told Reuters.

Nationwide: Ukraine's defence ministry said its forces had hit "six strategic refineries" up to 1,600 km behind the front line in one week. It did not name them.

Nationwide: plants reported halted or cut this month account for about 121.6mn tonnes a year, or 37% of Russia's 327mn tonnes nameplate capacity, by IntelliNews' refinery ledger, and up to 159.2mn tonnes, or 49%, if earlier halts still hold. The unconfirmed Ilsky halt is not counted. Deputy Prime Minister Alexander Novak said in early September that about 10% of Russian refining capacity was under repair.

Metal plants hit

Kryvyi Rih: ArcelorMittal said on September 25 that it could not safely and sustainably restart ArcelorMittal Kryvyi Rih after multiple recent missile strikes and expects an impairment of about $1bn, the Kyiv Post reported. The plant has capacity of about 6.5mn tonnes of steel a year and produced 4.92mn tonnes in 2021, by Global Energy Monitor's figures.

The status of 38 Ukrainian steel, iron ore, coke, ferroalloy, pipe and non-ferrous plants is tracked in IntelliNews' metals and mining ledger, linked below.

Factories and military targets in Russia

Rostov region: the Security Service of Ukraine (SBU) said its Alpha unit and the navy hit the Azov Optical-Mechanical Plant, part of Russia's Tactical Missiles Corporation, overnight into September 26 with Neptune cruise missiles and Ruta, Palianytsia and Bars missile-drones, damaging its optical and foundry production, an assembly area, an electroplating workshop and a printed circuit board facility, United24 reported. Ukraine's military intelligence says the plant makes radar seekers for guided missiles, thermal imaging equipment and electronics for precision artillery. Zelenskiy confirmed the strike.

Rostov region: Governor Yuri Slyusar reported a drone attack on Azov that injured four people, including a child, and damaged apartment blocks, homes, industrial enterprises, a school and a palace of culture, AiF Rostov reported. He did not name the plant.

Occupied Donbas: Ukraine's General Staff said its forces hit an ammunition depot in Sievierodonetsk in the Luhansk region and a P-18 Terek air-defence radar near Semenivske in the Donetsk region on September 25 and overnight, Ukrainska Pravda reported.

Nationwide: Russia's defence ministry claimed its air defences destroyed 96 Ukrainian drones between 20:00 on September 26 and 08:00 Moscow time on September 27 over the Belgorod and Kursk regions, Crimea and the Black Sea, Izvestia reported, after claiming 105 during the day on September 26.

Sochi: Rosaviatsia imposed temporary restrictions on flights at Sochi airport overnight, EADaily reported.

Ukraine under fire

Kyiv: a drone hit an uninhabited residential building in the Shevchenkivskyi district at about 22:00 on September 26, and overnight a warehouse and a car service centre caught fire in Solomianskyi. One man was killed and a woman injured, the State Emergency Service said, the Kyiv Independent reported. It was the third consecutive day of attacks on the capital.

Kyiv: On September 26, five people were injured in four districts, a drone hit a shopping and entertainment centre in Sviatoshynskyi, a fire broke out near warehouses in Darnytskyi and 20 people were evacuated from a residential building in Solomianskyi, Klitschko said, the Kyiv Independent reported. Russian strikes on data centres forced the TV channels Novyny.Live and Armiia TV to suspend broadcasting, and the Darnytsia pharmaceutical plant was hit for the second time in a week, with no casualties. Russia has been targeting Kyiv's data centres since September 25.

Kyiv region: Russia's defence ministry claimed it hit a Zammler Group logistics centre in Krasylivka that it said stored Western military aid, TASS reported. The monitoring account AMK Mapping posted footage of a large fire at a logistics warehouse in the village. No Ukrainian official named the site; the Kyiv Independent reported 23 facilities damaged in the Kyiv region over the past day.

Odesa region: Governor Oleh Kiper said Russia launched a "mass strike" that damaged a residential building, a medical facility, a hotel, a shop and a grain storage facility, killing one person and injuring two, the Kyiv Independent reported.

Sumy: three guided aerial bombs hit an administrative building next to residential high-rises and a disused cafe in a park in the city centre on September 26, killing two people and injuring 23, including four children, the city and regional military administrations said, NV reported. The Kyiv Independent later put the number injured in Sumy at 28.

Poltava region: power lines were damaged and 500 customers temporarily lost electricity, the Kyiv Independent reported.

Western border: Ukraine's infrastructure ministry is preparing an agreement with Poland that would let Ukrainian border and customs officers work on Polish territory, a step it said "is becoming particularly relevant amid constant Russian attacks on the Ukrainian border and transport infrastructure", Ukrainska Pravda reported on September 26.

Data centres, telecoms, media and R&D

Russia has added a new set of targets to its air campaign: Ukraine's data centres, telecoms operators, internet providers and media. The strikes are aimed at stymieing Ukraine's communications and the development of its military-grade technology, particularly AI-assisted weapons, as part of Moscow's effort to bring the Ukrainian economy to a standstill as winter approaches in the new "total war" phase of the conflict.

A key Kyiv data centre was damaged as early as July 2, but the campaign became systematic in September. "This is the beginning of a phase where, since September, they have started taking it out systematically," Anatolii Frolenkov of the 1-IX internet exchange told the Kyiv Independent. Drones hit the We Are Ukraine TV newsroom on September 8 and a Kyivstar building on September 11, and a strike on September 23 damaged at least three Kyiv data centres, cutting fixed-line internet to about 100,000 households. Zelenskiy said on September 25 that decisions had been taken to protect data centres and critical communications infrastructure, Ukrinform reported. IntelliNews' new ledger, linked below, logs 23 strikes and claimed strikes since July.

Kyiv: "This morning, the Russians struck a data center in Kyiv twice. Three people were injured in the first strike, including two children," Zelenskiy said on September 27, UA.News reported. Klitschko said a non-residential building in the Shevchenkivskyi district was hit and a woman and two 16-year-olds were injured, the Kyiv Independent reported. The operator was not named.

Russia's defence ministry said it hit a Vodafone data centre in Kyiv that it described as one of the largest providers of mobile and internet services to Ukraine's military, TASS reported. A drone hit a building housing a large Vodafone technical office in the Shevchenkivskyi district, a Ukrainian mobile industry community reported, according to dev.ua. Vodafone Ukraine had not commented.

"Unfortunately, following this morning's hostile strike, our data center was hit again. All employees are safe," the Cosmonova data centre said on September 26, Ukrinform reported. The outage took the TV channels Novyny.Live and Armiia TV off air and disrupted video playback on the public broadcaster Suspilne's website, the Kyiv Post reported. Russia's defence ministry claimed Cosmonova supported Starlink communications for Ukraine's armed forces.

The internet provider Kolo.TV was hit for the third time on September 26 and said the situation was "far more difficult this time", Mediasat reported.

A Russian ballistic missile significantly damaged the drone production workshop of Pegasus Arms on the night of September 23 to 24, the company said in a statement. It was the second attack on its production facilities, after which production had been relocated and restored; production is now suspended indefinitely.

Weapons and technology

Russia plans to spend $12bn next year on producing jet-powered drones and loitering munitions, Zelenskiy said on September 26, citing Russian internal documents obtained by Ukrainian military intelligence, the Kyiv Independent reported. Ukraine is intercepting 55% of jet-powered Shaheds, against more than 90% of conventional ones, he said. "In September more than 2,730 jet-powered Shaheds were launched, and over 1,500 of them were shot down or jammed," he said, Ukrainska Pravda reported.

Ukraine launched about three times as many long-range drones at Russia as Russia launched at Ukraine in the 100 days from June 17 to September 24, a Kyiv Post analysis of open-source strike data found. Ukrainian data recorded around 16,000 Russian drones launched in the period, while Russian defence ministry claims put the Ukrainian long-range drones shot down or neutralised at between 48,000 and 55,000. The paper cautioned that Moscow's figures are incomplete and prone to overcounting.

Russia's newer Geran-5 jet-powered drone can reportedly reach speeds of up to 600 km/h, has an estimated range of up to 950 km and can fly at up to 6,000 metres, the Kyiv Independent reported.

"We will invest in defense tech companies, launch our own technology projects, create R&D capabilities, test solutions together with the military, and scale up as quickly as possible the things that actually work on the battlefield," former defence minister Mykhailo Fedorov said on September 26, announcing an "Army of Robots" initiative modelled on the Army of Drones, the Kyiv Independent reported. He set a goal of the first assault on an enemy position with no infantry involved within 12 months.

Most of the companies involved in producing Russia's Molniya drones, and most of those supplying their components, are not yet under Western sanctions, the Center for Defense Reforms, a Ukrainian think tank, found in research shared with the Kyiv Independent.

The Ukrainian electronic-warfare maker Unwave tested four of its jamming systems against candidate drones at Fort Carson in Colorado from August 24 to September 2 under the Pentagon's Drone Dominance programme, which aims to buy more than 200,000 drones by 2027, Euromaidan Press reported. Fourteen drone makers and three electronic-warfare firms took part.

Arson and sabotage in the EU and the UK

UK: prosecutors at the trial of Joshua Cambridge, a 31-year-old British citizen charged with attempted sabotage, allege he passed information on a drone manufacturing facility in Swindon and the coordinates of four such facilities to Aiden Minnis, a Briton fighting for Russia whom investigators believe is cooperating with the GRU, Belsat reported, citing the BBC. Cambridge's lawyer denies the charges.

Romania: a drone entered Romanian airspace near Chilia Veche in Tulcea county overnight into September 27 and flew for several minutes almost parallel to the Chilia branch of the Danube before radar contact was lost near Pardina, the defence ministry said, Gazeta de Sud reported. Two Spanish F-18s and a Romanian IAR-330 helicopter were scrambled. No damage was reported and the drone's origin was not stated.

Germany: UPDATE: investigators suspect Russia's GRU military intelligence was behind the September 3 arson attack on a construction site near the Munich headquarters of Rohde & Schwarz and the drone maker Helsing, and that it recruited the two suspects detained, a 28-year-old woman and a 38-year-old Bulgarian man, the Frankfurter Allgemeine Zeitung reported, citing security officials, according to Meduza. Nobody was injured. No charge of GRU involvement has been announced.

Slovakia: UPDATE: the GRU was also preparing an attack on a factory of the Ukrainian drone maker Skyeton in Haniska, the newspaper reported. Slovak prosecutors said in late August that someone had tried to set the factory on fire, and three people, two Latvian citizens and a Ukrainian, have been detained, Meduza reported.

Finland and Sweden: Update, September 24: Finnish F/A-18 Hornets and Swedish JAS 39 Gripens together intercepted a Russian Tu-134 transport aircraft escorted by MiG-31 and Su-30 fighters in international airspace over the Gulf of Finland, the first joint mission of its kind, Finnish Defence Forces said.

Tit for tat

Ukraine is hitting Russia's refineries and the plants that make the guidance for its missiles. Russia is hitting Kyiv's data centres, internet providers and broadcasters, and has struck the capital three nights running.

"If the Russians have chosen to make their strikes even more brutal, the world must choose stronger responses to keep the war from spreading further," Zelenskiy said, calling for new US and EU sanctions, Ukrainska Pravda reported. Estonian Foreign Minister Margus Tsahkna said a Russian drone strike on a logistics facility serving McDonald's was "yet another clear sign that Moscow has no interest in peace".

Zelenskiy said Russia's plan to spend $12bn on jet drones next year shows Moscow is not preparing to stop the war "at least for now".

The ledgers

The running ledgers are kept as six public spreadsheets at permanent addresses. The first three are non-exhaustive, every row is sourced, and where only one side has spoken the row says so. Defence ministry figures are recorded as claims, and in the sabotage ledger attribution is given exactly as the authorities state it and no further. The fourth tracks what has happened to Ukraine's steel, iron ore, coke, ferroalloy and non-ferrous plants since 2021, grouped by owner. The fifth, started on September 27, follows strikes on data centres, telecoms, media and research sites.
