There was a big problem at night. Many websites were gone. This affected all pages with .de. People could not send any emails. Apps on the phone did not work.
The company Denic had a problem. Denic manages all web addresses with .de. This includes over 18 million websites. The problem started on Tuesday evening at 22 o'clock. A service called DNS-Service had an error. This service helps computers find the right website.
Computers do not find websites without this service. It works like a book with phone numbers. You type a name. But the computer finds no link. Secure pages had many problems. Denic looked for the error immediately.
The problem was over at 2 o'clock at night. All websites worked again. The experts do not know the reason yet. They check the problem now. Such problems happen from time to time.
