Wednesday’s disruption, caused by damage to broadband cables at a rail location in northern Frankfurt, forced Europe’s biggest airline by fleet size to ground hundreds of flights worldwide. Lufthansa’s global flight operations center is located on the outskirts of Frankfurt’s airport, so damage to the communications links there ripple through Lufthansa ground IT systems across the world. In Germany, air traffic control had to divert landings in Frankfurt to prevent an overflow.
Deutsche Telekom spokesman Peter Kespohl said that since Tuesday, four broadband fiber cables had been damaged at a Deutsche Bahn railtrack by drilling work neither commissioned nor conducted by the telecommunications company. Deutsche Telekom has repaired two of the cables and is working on the others, Kespohl said, adding the company couldn’t immediately say how long it will take to finish the repairs.
