Russia Knocks Ukrainian News Channels Offline as Moscow Steps Up Attacks on Kyiv’s Data Centers

What is a data center, and why do television channels, news websites, and internet services depend on it?

A data center is a facility filled with computers, storage systems, and networking equipment. It stores information and processes requests for websites, apps, broadcasts, and internet services. Television and news outlets often rely on these systems to deliver video, publish updates, and connect audiences. Damage can therefore affect much more than one company’s files.

Cosmonova’s facilities illustrate this dependence. After they were damaged, several television broadcasts were disrupted, including Army TV and Novyny.LIVE. Suspilne also reported video playback problems on its website. The data center’s equipment helps move content between the outlet and its audience. If that equipment fails, viewers may be unable to watch a broadcast even when the channel itself is still operating.

Cosmonova said it was redirecting internet traffic and restoring data from backup locations. Other services, including some websites and social media platforms, remained available. This shows why data centers need backups and alternative routes. Those protections can reduce downtime, but restoring full service may still take time when traffic shifts suddenly.

What services were disrupted after Cosmonova’s facilities were damaged?

The Cosmonova damage disrupted services that depended on its facilities. Reported effects included television interruptions, website video playback problems, and wider internet-service difficulties. These outages matter because people use broadcasters and news websites for timely information, especially during a war. A damaged technical facility can interrupt delivery even when journalists and programs are still operating.

Channel 24 reported that Army TV was affected. Television broadcasting for Novyny.LIVE was unavailable, although its website and social media platforms remained operational. Suspilne, a major Ukrainian news outlet, experienced video playback problems on its site. The local channel We - Ukraine+ was reported as available at the time. The different outcomes suggest that services may use separate infrastructure or have different backup arrangements.

Cosmonova said it was working to redirect internet traffic and restore data in backup locations. That process can bring services back gradually rather than all at once. The incident also shows why media organizations need multiple delivery paths. If one facility fails, alternative systems can preserve at least part of their broadcasts and online presence.

How extensive have the attacks on Ukrainian data centers been, including how many were reportedly hit in one day?

The attacks were not described as an isolated strike. A Ukrainian tech consultant told dev.ua that Russia had been hitting Ukrainian data centers for around three weeks. This indicates a continuing campaign against infrastructure that supports communications and digital services. The article does not provide a complete count of all affected facilities, so the reported figures should not be treated as the total scale.

The clearest single-day figure came from an attack on Wednesday. Four data centers were reportedly hit that day. Train service was also affected during the same attack. Earlier reporting described Cosmonova’s main facilities as damaged on Saturday, with disruptions reaching television channels, news websites, and internet services.

The repeated strikes create a broader resilience problem. Even when some equipment survives, traffic can shift suddenly to the remaining facilities. Frolenkov said this can overwhelm those nodes and cause further disruptions before traffic is redistributed. Backup sites and redundancy may limit the damage, but continuing attacks can test those protections and lengthen recovery times.

Why could damage to a data center affect people’s access to emergency information, such as air-raid sirens and news broadcasts?

Data centers support the digital systems people use to receive urgent information. They may host websites, video platforms, communications services, and other infrastructure that carries alerts or news. If those systems lose power, connectivity, or stored data, people may not receive warnings promptly. That makes a technical strike a public-safety problem, not merely an inconvenience.

The article points to the 2023 cyberattack against telecom operator Kyivstar. After parts of Kyivstar’s IT infrastructure were wiped clean, sirens were not active in certain areas. In the newer Cosmonova incident, Suspilne had website video playback issues, and some television broadcasts were unavailable. These examples show how failures can block different information channels at the same time.

The risk grows when several facilities or network routes are hit. Remaining nodes may face a sudden traffic spike, which can overload them before service is restored and redistributed. Backups, alternative facilities, and rerouting can improve resilience. However, the article shows that recovery may still be uneven, leaving some people without critical information temporarily.

Why did Russia say it targeted Cosmonova’s data centers?

Russia’s defense ministry said it targeted Cosmonova because the data centers allegedly supported Ukrainian military communications. Specifically, it claimed the facilities provided mobile internet service and support for the Starlink satellite communications system used by the Ukrainian Armed Forces. This was Russia’s stated justification for the attack, not an independently established finding in the article.

The alleged military connection helps explain why the facilities were selected, but the reported effects reached civilian services. Channel 24 said Cosmonova’s disruption affected television and news channels. Suspilne experienced video playback problems, and Novyny.LIVE television was unavailable. The article also connects data-center damage with wider concerns about people’s ability to receive information during the war.

Cosmonova said it was redirecting traffic and restoring data from backup locations. That response indicates the facilities supported more than one visible service. The incident shows how infrastructure with a claimed military role can also carry civilian communications. Any future strikes or outages could therefore affect both military connectivity and public access to news and online services.

How can backup locations, alternative data centers, and traffic rerouting help restore services after one facility is knocked offline?

Backup locations and alternative data centers provide a second place to store information and operate services. If one facility is knocked offline, organizations can recover data from another site and use different equipment to serve users. Traffic rerouting changes the path that requests take, directing them away from the damaged facility. Together, these measures can reduce the length and reach of an outage.

Cosmonova said it was working to redirect internet traffic and restore data in backup locations after its main facilities were damaged. The article also says certain redundancy features were already in place. These protections could help preserve websites, broadcasts, or other services even when one site fails. They do not necessarily restore every function immediately, especially if systems need to be checked or reconfigured.

The main challenge is imbalance. When traffic moves away from a failed facility, other nodes may receive far more requests than usual. Frolenkov said the remaining nodes could become overwhelmed before traffic was restored and redistributed. Recovery therefore depends on spare capacity, working backups, and careful traffic management.

What are internet traffic, network nodes, and redundancy, and why can the remaining nodes become overwhelmed when some facilities fail?

Internet traffic is the data moving between people’s devices and online services, such as a news video or website. Network nodes are connection points, servers, or facilities that help receive, process, and forward that data. Redundancy means having extra systems or routes available if one fails. These concepts matter because digital services depend on many linked components rather than one single machine.

When a data center goes offline, traffic can be redirected to other nodes. For example, Cosmonova was working to redirect internet traffic and restore data in backup locations after its facilities were damaged. The surviving nodes then handle requests that would normally have been distributed across more facilities. If they have enough spare capacity, services can continue with limited disruption.

The article says traffic could spike at certain nodes when facilities were knocked offline. Those nodes might become overwhelmed before service was restored and redistributed. This explains why redundancy reduces risk but does not guarantee uninterrupted service. A resilient network needs backups, alternative routes, and enough capacity to absorb sudden demand during attacks or failures.
