A fault in the core server of the city airport in the afternoon and a thunderstorm late on Monday evening disrupted flights, inconveniencing thousands of passengers, airport officials said.
The thunderstorm forced the Calcutta air traffic control to divert five city-bound flights.
The server fault, which was detected around 5.15pm and could not be fixed even late at night, led to delay in the departure of around 30 flights.
“One of the functions of the core server is to run the check-in system. Online check-in was disrupted and the flight information display boards went blank because of the snag,” an airport official said.
