Brown out
So in the almost 9 months I have been in Germany, today was the first day we had an unannounced internet and power outage. Total 3 minutes of power outage, and around 10-12 minutes of no internet. There have been no power outages at all, and the internet has been turned off for about 2-3 hours a couple of times for maintainance, which was hardly noticeable. I like it how they are able to maintain things so well.
