 An onion hosting Tor instance is reporting strange stuff for the last 3
 days. The server was attacked (DOS / SYN Flood last days), so maybe this
 could have triggered some network connection changes but the connection
 remained active / online. The torrc is very simple:
 {{{
 SocksPort 127.0.0.1:9050
 ControlPort 0
 HiddenServiceDir /var/lib/tor/tor_hs
 HiddenServiceVersion 2
 HiddenServicePort <port> 127.0.0.1:<port>
 }}}


 #1
 {{{
 May 12 11:16:08.000 [notice] Your network connection speed appears to have
 changed. Resetting timeout to 60s after 18 timeouts and 362 buildtimes.
 May 12 22:20:32.000 [notice] No circuits are opened. Relaxed timeout for
 circuit 398807 (a Hidden service: Connecting to rendezvous point 4-hop
 circuit in state doing handshakes with channel state open) to 106324ms.
 However, it appears the circuit has timed out anyway. [16 similar
 message(s) suppressed in last 3600 seconds]
 }}}

 #2
 {{{
 May 13 11:05:36.000 [notice] No circuits are opened. Relaxed timeout for
 circuit 399137 (a General-purpose client 3-hop circuit in state waiting to
 see how other guards perform with channel state open) to 106324ms.
 However, it appears the circuit has timed out anyway. [27 similar
 message(s) suppressed in last 3600 seconds]
 }}}

 #3
 {{{
 May 14 21:27:36.000 [warn] Failed to find node for hop #1 of our path.
 Discarding this circuit.
 May 14 21:27:36.000 [notice] Our circuit 0 (id: 400112) died due to an
 invalid selected path, purpose General-purpose client. This may be a torrc
 configuration issue, or a bug. [8 similar message(s) suppressed in last
 3600 seconds]
 }}}

 I wish I could reproduce the last one. Could this be a bug that occurs
 when our primary #1 Guard is in consensus but not reachable just for a
 certain machine / IP?
