| Date | Company / facility | What happened |
|---|---|---|
| Oct. 4 | Ukrtelecom, Dnipro | unverified Russian forces struck a communications-company premises in central Dnipro on the morning of Oct. 4, causing a fire. The Dnipropetrovsk regional military administration confirmed the attack on a communications company but did not name it. Ukrainian and local reports identified the building as Ukrtelecom, while that identification had not been officially confirmed by the authorities at the time of reporting. Information on casualties and the extent of damage was still being clarified. Source: UNN |
| Oct. 1 | Dline.ua / Dream Line | operator-reported Dline.ua said its data center at 28 Predslavynska Street in Kyiv was destroyed in a Russian strike. The company said all services and customer data were transferred to backup sites. Source: Dline.ua, via Ukrinform |
| Sept. 30 | Institute for Nuclear Research / Ukrainian Nuclear Data Center | confirmed by officials A Russian UAV struck the grounds of the Institute for Nuclear Research of the National Academy of Sciences of Ukraine in Kyiv, where the VVR-M research reactor is located. Ukrainian nuclear regulators said the reactor and its safety systems were not damaged and radiation levels remained normal. The institute hosts the Ukrainian Nuclear Data Center (UkrNDC), a subdivision of its Neutron Physics Laboratory, which maintains and compiles nuclear-data resources. This entry records an attack affecting scientific data infrastructure, rather than a conventional commercial data-center strike. |
| Sept. 30 | De Novo | Russian claim Russia's Defense Ministry said an overnight strike hit the De Novo data center in Kyiv, describing it as a major communications and internet-traffic facility. Reuters reported the claim but said it could not independently verify the extent of damage. De Novo's own website identifies its Kyiv site as a commercial data center and cloud facility. Status: Russian claim, physical damage not independently confirmed. Source: Reuters |
| Sept. 29 | Lanet | operational impact Lanet temporarily closed its Kyiv customer service center for security reasons, citing the safety of employees and visitors. The provider said its network continues to operate normally and customers can receive assistance remotely through online services and other communication channels. The company has not given a reopening date. This is an operational security measure, not a reported physical strike or confirmed network outage. |
| Sept. 28 | Dobrobut / Ukrtelecom | confirmed by officials Dobrobut confirmed that its branch at 40 Antonovycha Street in Kyiv was hit in the morning attack. Ukrtelecom's Kyiv branch is also officially listed at the same address. This establishes Ukrtelecom's presence at the building, but does not establish that Ukrtelecom equipment or offices were damaged. Source: Interfax-Ukraine |
| Sept. 27 | Varyag video | official claim Russia's 50th Separate Brigade "Varyag" published a video showing strike sequences it identifies as attacks on 11 Ukrainian data-center or network facilities: De Novo, PrivatBank, Kyivstar, United DC, Cosmonova, G50/NEWTELCO, Inter Cars, BeMobile, Datagroup, Parkovy and Volia. Several are independently documented elsewhere in this chronology. The video is evidence of the brigade's claimed strikes, not by itself of the extent of damage or service disruption at each facility. Source: 50th Separate Brigade Varyag |
| Sept. 27 | Kyivstar | confirmed by officials Kyivstar's press service confirmed that the building housing the company's main office in Kyiv was damaged in the morning attack. The company said no one was injured. This is confirmed damage to telecom infrastructure, not a confirmed separate data-center strike. Source: Interfax-Ukraine |
| Sept. 27 | Kyivstar | Later, local Telegram channels reported that another Kyivstar data center had been attacked. The report is recorded as preliminary and has not been independently verified. |
| Sept. 27 | Vodafone | Russian claim The Russian Defense Ministry reported that a Vodafone data-processing center in Kyiv had been hit, claiming it supports mobile communications and high-speed Internet services for the Armed Forces of Ukraine. Separately, dev.ua reported that the Telegram community MZU said a drone struck a building in Kyiv's Shevchenkivsky district housing a large Vodafone technical office. Vodafone declined to comment to dev.ua. Vodafone's own news page had no statement confirming damage as of the latest check. This remains an attributed claim, not a confirmed physical data-center damage report. Source: Reuters |
| Sept. 27 | Government internet resilience | official claim Prime Minister Serhiy Koretsky said Ukraine must plan for the worst-case scenario in protecting its internet infrastructure. He said some infrastructure should be in the cloud, some abroad, and some in combinations of the two or all three approaches. |
| Sept. 27 | Kyiv data center | official statement President Volodymyr Zelenskyy said Russian forces shelled a data center in Kyiv twice during the morning.

| Sept. 26 | Data centers / critical communications infrastructure | official statement Following a meeting of the Staff, President Zelenskyy said additional decisions had been made to protect and ensure the uninterrupted operation of Ukraine's data-center infrastructure and other facilities critical to communications. He said full implementation of the decisions at all levels was the personal responsibility of government officials and the heads of the security services. |
| Sept. 25 | Parkovy data center | operator-reported Parkovy Data Center said in a statement published on its Facebook page that repeated Russian strikes caused critical damage to its Kyiv site and forced it to cease operations there. The company said services at the site cannot currently be restored, while customer data is held at backup facilities in the EU. This is an operator-confirmed physical data-center damage and shutdown. |
| Sept. 25 | Inkom business center / Datagroup | unverified A Russian drone struck the Inkom business center at 31/33 Smolenska Street (now Simyi Brodskykh Street) in Kyiv. The seven-storey, multi-tenant office building houses offices of different companies. Datagroup was reported as a tenant. The building itself is also associated with PrJSC Information Computer Systems (INCOM), whose registered and actual address is 31/33 Smolenska Street. The strike is relevant to the wider sequence of attacks on Kyiv's telecom and data-center infrastructure, but the available reporting does not establish that the entire building was a data center or that every tenant's equipment was hit.

| Sept. 25 | National network | official statement Presidential adviser Serhiy Beskrestnov said Ukraine's highly distributed Internet network should prevent a nationwide or citywide loss of Internet access despite attacks on communications infrastructure.

Corrections: Oct. 5, 2026 — removed the duplicate Dline.ua entry and corrected the update date. Oct. 4, 2026 — retitled and widened the scope to “Kyiv and selected Ukrainian data center and network infrastructure damage,” added an explicit scope note for the Oct. 4 Dnipro/Ukrtelecom entry, added status labels, row anchors, source links, share-preview metadata and a last-updated line. Earlier changes — clarified the Sept. 30 nuclear entry as scientific/data infrastructure rather than a conventional commercial data-center strike, and distinguished operator-reported damage, operational disruption and Russian claims.
Working chronology, newest first. Compiled by abdymok. Company-reported infrastructure damage is not necessarily evidence of a separate physical data-center strike. Downstream service outages are listed separately from physical damage reports. The Sept. 25 Inkom entry is based on reporting that Datagroup occupied space in the multi-tenant Inkom business center, and on public registration data identifying PrJSC Information Computer Systems (INCOM) at the same address. It does not establish that all tenants or all equipment in the building were affected. The Sept. 27 Vodafone entry records an attributed claim and reported damage to a Vodafone technical-office building, but not a confirmed physical data-center strike.
