Tor Exit Nodes in Libraries – Pilot

One interesting thing I read recently is that, when building a circuit, Tor actively avoids picking more than one relay sharing a common attack vector.

Basically, it will not pick more than one relay with the same family id, router or /16 subnet.

Your point is still valid, since AWS and other big web hosts like OVH obviously have a lot of /16 subnets and distinct router addresses, but it's good to see this was anticipated by the design.

Yeah, that's super interesting.

To be fair, I suspect there is already a similar problem simply due to economics: running a relay costs money, so the vast majority of relays are running in the first world, which correlates well with countries that have extradition treaties with the US, for example.
