@Green Thank you - couldn’t handle 'attack vector' as a synonym for ""method or type of attack" :-)
Additional to that is it clever for a supporter of TOR to to run more than one Relay (Exit) with a single ISP or even AS https://en.wikipedia.org/wiki/Autonomous_system_(Internet) or does this build a kind of new attack vector?

@Paul: sure. Nils pointed out that a lot of relays using the same hosting provider could be an attack vector, because the provider would be a single point where all the relays' secret keys could be collected. My point is that if you look at the AS (Autonomous System) Number, it's normally the same for all the hosting provider's servers in that country. So if Tor path selection looks at the AS, and avoids building a circuit that uses two nodes from the same AS, this attack vector basically goes away. It's worth noting if you weren't already aware, both Atlas and Globe display the AS Number for every relay.
