If I know the relays IP I could give you the probabilities of your relay relaying traffic to others in the same AS (since a relay will usually not be used with others in the same /16 netblock)
It'd be better for relays to avoid connecting within an AS, right?
better according to what metric?
Rather than just within /16. Or at least, if there were enough AS diversity. Which I'm guessing there isn't. So that would limit the number of possible circuits too much. Is that accurate?
it will certainly limit the possible circuits a lot since the biggest 10 autonomous systems make up about 50% of the entire tor network.
