A fire at a Delhi data centre operated by STT Global Data Centres India and associated with Tata Communications has caused significant disruption for several customers, with some firms reporting difficulties in recovering data and restoring services. While initial assessments indicate the incident was confined to a single data hall, recovery efforts remain ongoing. The fire also affected network infrastructure used by Google Cloud and other businesses, highlighting the operational risks associated with critical digital infrastructure.
A fire at a Delhi data centre jointly operated by STT Global Data Centres India and Tata Communications continues to affect customers nearly three weeks after the incident, with several businesses reporting challenges in restoring data and normal operations. According to company communications reviewed by Reuters, the extent of damage in parts of the facility has complicated recovery efforts for affected clients.
The fire occurred on June 5 at a facility in Delhi that houses critical digital infrastructure for enterprises, cloud service providers and internet operators. Tata Communications had initially stated that business continuity measures were activated immediately after the incident to minimise disruptions and maintain services for customers using the facility. No casualties were reported.
However, some customers have indicated that restoring systems and retrieving data has taken longer than expected. Matrix Cellular, a provider of international communication services, stated that it may have lost access to more than two decades of operational and business data stored at the affected facility. Another customer, internet service provider R2 Net, reported financial losses and disruption to services linked to the outage.
The incident also affected network infrastructure used by Google Cloud. Following the fire, Google reported intermittent network disruptions and elevated latency affecting customers in Delhi, Mumbai, Chennai and nearby regions after an emergency shutdown of networking equipment at the facility. The company has since rerouted traffic and implemented mitigation measures, though service restoration efforts have continued.
According to Delhi fire authorities, the blaze is suspected to have originated in lithium battery units. STT Global Data Centres India has commissioned an independent technical investigation to determine the root cause, with findings expected in the coming weeks. The company said it is working with affected customers and, where possible, providing alternate capacity to support business continuity.
A preliminary assessment by Tata Communications and STT Global Data Centres indicated that the fire was confined to a single data hall and related infrastructure, while the remainder of the facility continued to operate. The company also stated that services for customers who had subscribed to backup and recovery solutions had been restored.
The incident has drawn attention to the growing importance of data resilience, backup systems and disaster recovery planning as India's digital infrastructure sector continues to expand. With data centres supporting cloud computing, enterprise applications and digital services across industries, operators and customers are expected to review contingency measures and operational safeguards in the wake of the disruption.
