Germans have a reputation for technical prowess. You’d expect the operators there to be technically superior in delivering what they promised when they sold broadband service. But it appears that they have not been so, according to a New York Times report. A government study released Thursday supports what many German consumers have long suspected: Internet broadband service is much slower than advertised. The study by the German telecommunications regulator, the Bundesnetzagentur, measured the Internet connection speeds of 250,000 consumers from June through December last year, making it one of the largest reviews of broadband service anywhere.
