Centre for Development of Telematics, also known as C-DOT, is a state-owned telecommunications technology development centre headquartered in India. Established in 1984 and employing approximately 320 individuals, the organization functions as an Indian Government owned entity primarily focused on the development of telecommunications technology. Initially mandated to design and develop digital exchanges, C-DOT has expanded its focus to include the creation of intelligent computer software applications. It maintains offices in Delhi, Bangalore, and Kolkata, and has been appraised at Maturity Level 5 of CMMI-DEV v1.3.
India's Cell Broadcast Alert System, developed by the Centre for Development of Telematics (C-DOT) in collaboration with the National Disaster Management Authority (NDMA), faced temporary suspension on June 16, 2026. This action followed reports of a technical glitch that allegedly delivered an emergency warning to unintended recipients, prompting concerns over the nationwide public warning network's reliability. The Hindu noted the suspension stemmed from a misrouted late-night alert, with authorities suggesting a technical malfunction as a potential cause. This temporary halt came after a June 13, 2026, advisory from the NDMA concerning the service, which had launched in May 2026 for real-time disaster alerts. Previously, on May 11, 2026, the Delhi High Court reserved judgment on a petition regarding the implementation framework of India’s emergency cell broadcast system. The system earlier underwent a nationwide trial on May 4, 2026, where millions of Indians received an "extremely severe" alert on their phones.
