Comment (by cypherpunks): Hello, for the inter-relay question. Please read code inside: {{{ +++ src/core/or/channelpadding.c @@ -617,7 +617,10 @@ channelpadding_get_channel_idle_timeout( }}} TL;DR {{{ Canonical relay-to-relay channels only last for 45..75min or consensus +/- 25% }}} I tested this and found out, that on extending through a relay, to a given node can have high cbt on first because TLS handshaking inter relay. Next CircuitBuildTime will be better, because multiplexing above existing orcon. But later used, the same behavior repeats! So, the relay could benefit from reestablishing the connections. giving better latency for circuits. This have no privacy impacts. Why don't just enable TFO in alpha branch for this TLS channels? -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/16682#comment:15> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
