Comment:

 I've updated the email (below), the wiki entry, and the fallback directory
 list (attached to #15775).
 (Do you think we should attach the list to the email as well as linking to
 it in the email?)

 A list of fallback directories would help with the following tickets:
 * fallback directories (#15775),
 * client boostrap reliability (#4483) and
 * clients on IPv6 (#17281).

 If the responses are on the list, I can add them to the whitelist (or opt-
 outs to the blacklist).

 If you do get direct responses, can you send me a list of relays that need
 to be added to the whitelist / blacklist (after removing anything written
 by the operators).

 Here is an updated draft email for tor-relays at tpo:

 Dear Relay Operators,

 We want to run a trial of fallback directory mirrors in Tor. Tor clients
 contact fallback directory mirrors during initial bootstrap, before they
 contact the directory authorities.

 Fallback directory mirrors allow Tor to bootstrap in networks that block
 the Tor directory authorities. This allows people to use Tor without
 manually configuring bridges or pluggable transports.

 For more information about fallback directory mirrors, see:
 https://trac.torproject.org/projects/tor/wiki/doc/FallbackDirectoryMirrors

 We want to find around 100 stable non-exit relays, as exits currently
 experience high load. (We don't want to overload exits, so we
 automatically reduce the likelihood that exits are used as fallback
 directories.)

 In December 2015, we created a list of candidate fallback directories. If
 your relay is on this list of candidates, and will be keeping its address
 and port for at least 2 years, we would like to put it in the fallback
 directory list. (We will also include the details of long-term relays that
 may become stable enough to be a fallback at some point in the future.)

 https://trac.torproject.org/projects/tor/attachment/ticket/15775/fallback_dirs.inc

 For the initial fallback directory release, we will only put your relay on
 this list if you give us permission. Please reply on the list. (Your
 relay's details will be added to the publicly available tor source code.)
