All flights are now leaving on time.
The airport set up whiteboards to direct passengers to their gates because sometimes low tech is the best solution to high-tech problems.
'Please use the temporary flight boards in the departure lounges or listen for airline flight announcements.
The UK's second largest airport, which serves 45 million passengers a year on short and long-haul flights, descended into farcical chaos today after a damaged Vodafone fibre optic cable took out the information screens and forced many passengers to get flight updates from hand-drawn white boards.
"Thank goodness I have eagle vision and can read messy writing from a distance".
Gatwick Express, which provides trains to the airport, said the issues "may result in screens around the station showing no information". "We are keeping Gatwick Airport constantly informed of progress". Why not pre-assign gates like Canadian airports?'
An airport spokesman apologised to passengers affected by the issue, adding that a "handful of people" had missed their flights.
