New Delhi data center fire disrupts Tata and Google Cloud services

The blaze broke out in the early hours of June 5, 2026, at STT Global Data Centres India’s Greater Kailash-I site in New Delhi.

It damaged parts of the facility badly enough to make recovery of data and systems difficult, and the outage spread into Google Cloud services carrying traffic from several Indian cities.

Delhi Fire Service was first alerted at about 2:45 a.m. to 2:47 a.m. Firefighters brought the fire under control, and no fatalities were reported. Two firefighters suffered burn injuries while battling the blaze, and Delhi fire authorities said lithium battery units were involved, though the precise cause remained unclear.

The site sits in a tower leased by Tata Communications and belongs to ST Telemedia Global Data Centres India, a joint venture that has been operating since 2004 and is owned 74% by STT GDC and 26% by Tata Communications. STT GDC India operates 10 data centers in India, and STT Delhi DC 3 in Greater Kailash is the only enterprise-grade data center in Delhi and a preferred site for government organizations.

Google Cloud said traffic originating from Delhi, Chennai, Mumbai and surrounding areas was experiencing intermittent elevated latency and possible packet loss after a fire at a third-party data center required an emergency power shutdown of networking equipment.

Matrix Cellular said it lost access to more than 20 years of operational and business records stored at the facility. The blaze caused losses running into hundreds of crores of rupees and affected traffic from Google, Netflix and several local internet service providers in the National Capital Region. R2 Net’s losses were estimated at $2 million.

Tata Communications told stock exchanges on June 5 that it had activated business continuity protocols to reduce disruption. The company said the damage had made recovery of affected data and systems very hard, leaving the timeline for restoration and the full extent of the loss uncertain.
