Comment (by arma):

 Replying to [comment:6 asn]:
 > FWIW, it's also worth mentioning that making HSes more stubborn towards
 old IPs might also allow guard discovery attacks from the IP. That is the
 IP kills incoming circuits, till a compromised middle node is selected,
 and since the HS is stubborn it will keep on establishing new circuits.

 That's why you should only stick to your intro point when it's your
 network that failed (that is, the connection between you and your guard),
 not the intro circuit. (This is what I meant in the body of the bug in the
 'main tricky point' sentence.)
