Patrick Lichty of net culture magazine Furtherfield calls it "magical (...) After watching Traceroute, I was left with a real exhilaration and a deeply reflective feeling at once. (...) What Traceroute reveals is the tradition of alterity just beneath the surface of Western culture, and that it has a powerful effect on our mass consciousness, whether it is in plain sight or not." Felix Knoke of Engadget Germany writes: "For me it is the best nerd documentary I've seen so far. Simply for the fact that it doesn't take itself as deadly serious as the other ones. (...) Traceroute deserves high praise because it represents an old-school definition of nerd culture, one that is never compatible with fintech, unicorn and iGod." Pop culture critic Thomas Kaestle comments: "Traceroute is game, challenge, encyclopedia, and sentimental journey all in one. As a documentary it is most skillfully composed. And as a narration it is highly compatible. This film will, in passing, sweep proclaimed nerds off their feet. And it will touch the hearts of those who still need some explanation." Diamond in the Rough Films praises Grenzfurthner's hosting and storytelling: "This doc works in some very unconventional ways, not the least of which is our plucky protagonist. Grenzfurthner is an absolute charmer as our host and his narration is note-perfect (the accent is so cool in that Werner Herzog kind of way). It's really rare in a documentary about a not-that-famous person where you become almost instantly won-over and invested in their personal journey." Blogger and sci-fiction author Cory Doctorow states about Traceroute that "Johannes is a brilliant lunatic of surpassing and delightful weirdness." MicroFilmmaker Magazine writes: "The different people Grenzfurthner chatted with were genuinely interesting and the organic way he moved from place to place was intriguing. [...] You'll find that you've learned an awful lot about technology, nerdiness, and America."
