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.
- kerkeslager 11y agoYeah, 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.
