 expansion over what you asked]. Stem now has a FallbackDirectory class
 with two methods for getting this information...

 [https://stem.torproject.org/api/descriptor/remote.html#stem.descriptor.remote.FallbackDirectory.from_remote
 FallbackDirectory.from_remote()] reads the latest fallback_dirs.inc from
 gitweb, providing the latest fallback directories in tor's master branch.

 > *
 [https://stem.torproject.org/api/descriptor/remote.html#stem.descriptor.remote.FallbackDirectory.from_cache
 FallbackDirectory.from_cache()] provides the latest fallback directories
 Stem has cached. This is only as up-to-date as your Stem release but is
 quicker and avoids relying on gitweb.

 In #16774, we added the fallback directories to GETINFO defaults. Tor
 0.2.8.1-alpha and later should be able to tell stem the fallback
 directories this way as well.

 > * Stem's descriptor.remote module now puts less load on the directory
 authorities since it uses fallback directories as well.

 FYI, tor currently tries to connect to 3 fallback directories in the first
 few seconds, then tries an authority. It downloads from the first one that
 connects, and cancels the others. See #4483.

 > Downloading the consensus took 30.80 from eriador

 That's not good, can doctor please report any fallback directories that
 take a relatively long amount of time to serve a consensus (like doctor
 does for the authorities), and report any that take more than 10 seconds?

 How can I get on a list that gets this output, or will it appear on IRC in
 #tor-bots?
