Hundreds of Lufthansa flights were grounded or diverted at Frankfurt Airport, Germany, due to a technical glitch at Lufthansa, Reuters reported.
A spokesperson of airport operator Fraport told the news agency that more than 200 flights were cancelled at Frankfurt, one of Europe’s largest airports.
Flag carrier Lufthansa blamed it on railway engineering works that damaged broadband cables.
The damage to the cables led to check-in and boarding problems.
Due to this glitch, German air traffic control (ATC) also temporarily suspended all incoming flights at the airport.
The problem was later addressed, with information technology (IT) systems rebooting and flight departures resumed at the airport.
Germany’s national train operator Deutsche Bahn blamed it on the third-party engineering works on a railway line extension, when a drill cut through a Deutsche Telekom fibre-optic cable bundle, according to the news agency.
The technical problems also led to the cancellation of a flight to Frankfurt from Amsterdam’s Schiphol Airport.
Deutsche Telekom said in a statement: “Two cables have already been repaired overnight by our technical team and many customers are already back online.”
In January, flights across the US came to a standstill after technical issues in the US Federal Aviation Administration (FAA) computer system.
The FAA system, which informs pilots about the hazards along a flight route, was unable to process updated information due to these issues.
Passengers reported delays and outages on flights via social media sites.
