Level(3) DNS Spoofing All Domains

Tue Nov 19 15:55:50 UTC 2019

Just to weigh in: Here in Germany, the largest internet provider (Deutsche Telekom) did the same thing.
It's basically just a "search guide", it redirects you to a search page and assumes you just had a typo in the URL.

Telekom stopped doing that in April, after a user reported them to the district attorney for supposed data manipulation, a misdemeanor.
