Lufthansa has made this announcement today:

Due to an IT failure many Lufthansa IT systems are currently not working. Because of this reason, passengers must expect disruptions in the flights program and during the check-in process. 

Important information on flight disruption: As of this morning the airlines of the Lufthansa Group are affected by an IT outage, caused by construction work in the Frankfurt region. Unfortunately, this has led to flight delays and cancellations. We are working on a solution swiftly. Until then we ask all affected guests flying on domestic LH flights in Germany to book a train ticket and request a refund on http://lh.com.
