It's not the machine where tor runs on.  It's the firewall/modem? thing
one before that.  This is obvious from the traceroute:

weasel@asteria:~$ tcptraceroute -f 13 213.17.104.91 443

No, that just means you use ECN on your outgoing TCP connections.  That
doesn't magically fix the hardware between the tor server and the
internet.
