During the Diwali celebrations, Delhi's air quality monitoring displays were found switched off, leaving residents without real-time AQI information. Authorities say technical glitches caused the outage.
On Diwali night, several air‑quality monitoring screens across Delhi were found turned off, depriving residents of real‑time AQI data during a period of already high pollution levels.
The Delhi Pollution Control Committee confirmed that a technical malfunction had disabled the displays, and that the issue was not related to power outages.
Officials said they are investigating the root cause and will restore the system as soon as possible, while also planning upgrades to the existing sensors.
Environmental groups have criticized the lack of transparency and urged the government to improve monitoring and public communication.
