It's the first test of its kind since Germany was reunified in 1991. From a report: According to the Office for Protection and Disaster Aid (BBK), the national emergency warning day is intended to test out Germany's warning systems and prepare the public for what to do in the event of a national emergency. "On the one hand, this is about conducting a technical test of the warning systems. The other is that we want to sensitize the population with the warning day. We want to give them an understanding of what such warning signals, such as the sirens, mean," said Christoph Unger, the head of the BBK.
While sirens wailed across many parts of Germany, the emergency test day saw a bumpy roll out in other areas -- particularly with more modern technology. It was the first time that nationwide emergency push notifications were due to be sent out -- but many users reported either not receiving a notification at all or getting one after a delay. "The nationwide MoWaS [Modular warning system] could only be received after a delay. The reason for this was an unscheduled simultaneous triggering of a large number of warning messages via MoWaS," the BBK wrote on Twitter The system uses a satellite system to send out warning messages to public broadcasters, news agencies, critical infrastructure companies -- and smartphone users with so-called "warning apps."
