Thousands of travelers in Germany were left stranded Wednesday due to an IT outage that impacted Lufthansa airlines. The outage was caused by a severed telecommunications cable with more than 200 flights canceled, according to reports.
Lufthansa said it was "affected by an IT outage, caused by construction work in the Frankfurt region," asking passengers to rebook travel within Germany on trains. More than 200 flights were canceled and 100 were delayed as a result of the IT outage.
It later said its IT system had rebooted and departure flights out of Frankfurt Airport had resumed. The airline said it expected the situation to be stabilized by the end of the evening, with Frankfurt flights back on track by Thursday. Lufthansa apologized to customers, asking them to rebook their flights scheduled for Wednesday.
Both Lufthansa and Germany's national train operator blamed the outage on engineering work being conducted on a railway line extension Tuesday evening, during which a Deutsche Telekom fiber optic cable bundle was cut.
Deutsche Telekom, Germany’s main telecom provider, confirmed that a cable was cut during the drilling.
The severed cable is said to have contributed to passenger check-in and boarding system issues on Wednesday. Incoming flights were suspended by German air traffic control as a result. Deautsche Telekom ensured technicians were "already on site" to resolve the problem in a tweet posted Wednesday.

"Our technicians are already on site. Due to the considerable damage and situation on the construction site, the remedy will be extremely difficult," the telecom provider wrote.
Other European airports reported cancelations as a result of the Lufthansa outage, with Paris Charles de Gaulle airport canceling two flights and Amsterdam's Schiphol Airport canceling one flight into Frankfurt.
