Comment:

 Onionoo now has a new [https://onionoo.torproject.org/
 "last_changed_address_or_port" field] which is a tweaked version of what I
 suggested above.

 Using Sathya's script, I created a list of 10 fallback directories which I
 think can be shipped with 0.2.5.x bundles.  Each relay in that list
 matches the following requirements:

 - has both an IPv4 and an IPv6 address,
 - has a non-zero DirPort,
 - is around for at least 180 days,
 - has not changed one of its IP addresses or ORPort/DirPort in the past
 180 days, and
 - doesn't have the Authority flag.

 Here's the list:

 {{{

 }}}

 Does this list look sane?

 I'm attaching the updated script that I used to generate this list.  Run
 it like this:

 {{{
 curl "https://onionoo.torproject.org/details?type=relay&running=true" >
 details.json
 python dir_list.py details.json fallback-dirs 180 180 20
 }}}

 Erinn, can you integrate this script and instructions into the build
 process for 0.2.5.x bundles?  Of course, as Nick says above, we'll want to
 test those new bundles before shipping.
