Two Kyiv Data Centers Hit Within Hours: Incident Report and Recovery Status

Posted on 2026-09-25

On September 23, 2026, both data centers hosting VSYS Host infrastructure in Kyiv were hit by russian missile strikes within a few hours of each other. This report covers what happened, what we found on site, what has already been restored, and what is still in progress.

What happened

Our Kyiv infrastructure was deliberately split between two independent data centers. The goal was to reduce the risk of a single facility failure taking everything offline.

On September 23, the first russian missile strike hit one of the data centers. A few hours later, the second data center was hit, and then hit again. Both data centers are now out of operation for an indefinite period.

These were not isolated hits. The strikes also affected other data centers where VSYS Host has no equipment. This was a wider russian attack on the data center infrastructure.

From the first hour, the team worked on three priorities: keeping the company operational, getting physical access to the equipment, and restoring customer services wherever technically possible.

Condition of the equipment

In the first stage of the incident we had no physical access to our hardware. We received updates from the data center teams, but we could not verify the state of individual servers ourselves.

Once our engineers reached the sites, the picture became clear:

• Data center 1: 100% of our equipment is physically intact.
• Data center 2: our equipment also survived and is physically intact, but some hardware shows signs of water exposure.

Hardware that may have been exposed to water cannot simply be powered on. Each unit needs inspection and careful handling first, otherwise we risk turning recoverable hardware into damaged hardware. Recovery is therefore going server by server, based on the condition of each machine.

Virtual services: most are already back online

Rather than waiting for the original facilities to reopen, we moved virtual infrastructure to another data center selected specifically for its security profile.

As of September 25, the majority of affected virtual services are already running in the new facility.

We are not disclosing its location. Even most VSYS Host employees do not know the address; access to this information is limited to the small group directly deploying and operating the infrastructure there. This is a deliberate measure to protect the new site, and we are confident it does not carry the same attack risk as the affected facilities.

Work on the remaining systems continues, including:

• VPS
• streaming services
• storage
• hosting
• other virtual services

Based on current progress, we expect 100% of affected virtual services to be restored within the next few days.

Dedicated servers: why this takes longer

Dedicated servers are a fundamentally different problem. Virtual services can be redeployed onto new hardware. Dedicated servers are the hardware, so they have to be physically moved to another facility before they can run again.

And we are talking about a very large fleet.

Finding a new home for it requires much more than free rack space. The facility needs enough:

• physical space
• power capacity
• cooling
• network connectivity
• operational staff and resources

On top of that, after losing two facilities in one day, we have one more requirement: the new location must not carry an unacceptable risk of a missile strike. We will not move a large volume of customer infrastructure to the first facility that happens to have space.

As of today, we have not found a facility that meets all of these requirements. The search is ongoing.

This is why there is currently no ETA for dedicated server restoration. Any estimate given before a facility is confirmed would not be reliable, and we would rather not give customers a date we cannot stand behind.

Once a suitable facility is secured, relocation will start immediately. Because of the number of machines, servers will come back progressively and in order, not all at once. Affected customers will be informed as each stage progresses.

Data access before full restoration

Many customers need their data now, not when their server is fully back in service. In parallel with the facility search, our engineers are working on a way to let customers copy data from their dedicated servers before full restoration.

What is technically possible will depend on the condition and configuration of each server, so there is no universal procedure yet. As soon as a workable process is ready, we will contact affected customers directly.

VSYS Host continues to operate

The company is fully operational. The team is working, support is available, services in our other locations are running normally, and we continue to provision new infrastructure.

We are seeing a sharp increase in requests to migrate services to our locations outside Ukraine, and we are helping customers move wherever capacity allows. Because of this demand, some dedicated server configurations outside Ukraine may soon be temporarily out of stock.

If you are planning a migration, contact our team to check current availability and migration options.

Status summary as of September 25

Thank you

We know how critical these services are to our customers and how disruptive their unavailability is. The team has been working around the clock to bring infrastructure back as quickly as possible, without cutting corners on safety.

Thank you for your patience, trust and support over these days. The most difficult part, dedicated servers, is still ahead. We will continue to report progress openly and share updates as soon as we have new information.
