Hi All,
Dominique, pastly, and Hello71 have offered to help out with this.
(I don't have Hello71's email, I'll ping them on IRC.)
Let's start by fixing up some of the code, and asking relay operators
if they want to be on the list.

pastly, I drafted an email for step 0, can you check it makes sense?
(I used to send out way too much info. I'm trying to be brief.)

Anyone can do step 1, it's a copy-and-paste job with git and a config file:
> 1. Update the fallback whitelist with new and changed relay details

Dominique, do you want to do Step 2?
It's a one-line patch that would be a good intro to Tor's bug tracker and git.
Please base it on the "master" branch.
> 2. Update updateFallbackDirs.py to have a CONSENSUS_EXPIRY_TOLERANCE of 0.
> Ticket: https://trac.torproject.org/projects/tor/ticket/20942
> File: tor/scripts/maint/updateFallbackDirs.py
There are two more optional tasks if someone likes python:
Mark the fallbacks that have extra-info descriptors, so stem can use them
https://trac.torproject.org/projects/tor/ticket/22759
Add fallback nicknames to the file, so stem can use them
https://trac.torproject.org/projects/tor/ticket/24600
> 3. Run updateFallbackDirs.py with the new whitelist and CONSENSUS_EXPIRY_TOLERANCE.
> You'll need a decent network connection for this.
> Please attach the script logs to the trac ticket.
> Command: tor/scripts/maint/updateFallbackDirs.py > src/or/fallback_dirs.inc
And there's another step here I forgot:
3a. Look at the warnings from the script to see which addresses have changed.
Contact operators to see if the new addresses are permanent.
Then repeat steps 1 and 3 with the new details.

Once this is done, the list gets backported to 0.2.8 and later.
But the rest of the changes go into master.
> 5. Announce the new list on tor-relays@
Example: https://lists.torproject.org/pipermail/tor-relays/2017-May/012285.html
> 6. Tell the relay search maintainer that the list has changed
