Comment (by teor):
On 3/3 of my OVH relays in Montreal (liskov0 is an exit, the others are
guards), this appears to have reduced the number of NTor circuits by by
30% as of Dec 22/23 local time (UTC-5). One of the guards (liskov1) had a
load spike around the time of the change.
Note that these relays have decent connectivity but more latency to these
new Tor clients, many of which are at OVH somewhere in France.
