Think of a data center as the digital equivalent of a bank vault. Now imagine that vault catching fire. That’s essentially what happened on June 5 when a blaze tore through the STT Global Data Centres India facility in New Delhi’s Next-Gen Tower, operated by ST Telemedia Global Data Centres on behalf of Tata Communications.

The damage was extensive. Client data was lost. Google Cloud users across India felt the ripple effects for days. And an independent investigation is still trying to figure out just how bad things really are.

What happened and who got burned

The fire erupted early on June 5 at the New Delhi facility. Tata Communications activated business continuity protocols the same day, notifying Indian stock exchanges about the incident.

Early damage assessments describe the destruction as “extensive,” with potential client data losses and equipment damage estimated in the hundreds of crores. For context, that translates to tens of millions of dollars.

To prevent the fire from causing even more damage, networking equipment underwent an emergency shutdown. That shutdown isolated a critical Point of Presence, or POP, in Delhi — one of the key nodes that routes internet traffic in northern India.

The consequences cascaded quickly. Google Cloud reported intermittent network disruptions and increased latency for users in Delhi, Chennai, and Mumbai between June 9 and June 11. When a single data center fire in Delhi causes lag in Mumbai and Chennai, roughly 1,400 and 2,200 kilometers away respectively, it tells you something uncomfortable about how concentrated India’s digital plumbing actually is.

Businesses beyond the tech giants were affected too. Matrix Cellular, among other companies, reported broader service disruptions tied to the incident.

India’s digital infrastructure under the microscope

As of June 24, an independent investigation was still underway to assess the full extent of the damage. The fact that nearly three weeks after the fire, investigators are still piecing together what happened, suggests the incident was more severe than initial reports may have indicated.

What this means for investors and the broader market

Tata Communications notified stock exchanges on the day of the fire, which means the company itself views this as material. Equipment replacement, client compensation claims, potential regulatory scrutiny, and reputational damage all represent real costs that will eventually show up on balance sheets.

Google Cloud’s multi-day disruption highlights a supply chain risk that investors don’t always price in. Google doesn’t own every building where its equipment sits. Neither do most major cloud providers. That dependency on third-party data center operators introduces a layer of risk that this incident has made very tangible.

Despite the scale of the disruption, there were no reported impacts on cryptocurrency networks or related tokens.
