The mobile phone network of Deutsche Telekom subsidiary T-Mobile collapsed across most of Germany on Tuesday. The network went down at around 4 p.m., interrupting mobile phone and text message services across most of the country.

A T-Mobile spokesperson in Bonn said just after 8 p.m. that two of three servers responsible for allocating telephone numbers to corresponding SIM phone cards had gone down. The spokesperson said it's unclear why the servers malfunctioned, but said the company would work through the night to restore services.

It's unclear how many people were affected. Around 39.1 million people use T-Mobile's D1-network. The company confirmed earlier that many people had been calling in to report disturbances.
