Traceroute requires support by all hops on the way, and that's not a given. Try pinging the DA's instead or connecting to their tor ports.
Only Dizum doesn't respond to ping requests, but it has a "welcome" page on 80.

OK, thanks for this extra insight. Still, the answer is consistent: I got ping replies only from longclaw, bastet and moria1. I was also unable to connect to dizum via HTTP (which I could from my work connection).
