The spokesperson did not give details about the nature of the problem, which comes amid reports of technical outages affecting some companies around the globe.
A large-scale outage also wrought havoc on IT systems across Australia on Friday, with the country’s national broadcaster, its largest international airport, and a major telecommunications company reporting issues.
The disruption ahead of the first weekend of the school holidays in Berlin came as US tech giant Microsoft said it was taking “mitigation actions” after service issues.
The UK’s biggest rail operator also warned of possible train cancellations due to IT issues on Friday morning.
