We've got three reports from users that their directory servers are unreachable, one on tor-relays, and two weird .doc files attached in #2699 and #2700. Since who knows what is actually in those .doc files, I've decided to open a new, more descriptive bug and dup those to it.

One fix for this is to devise a way to distribute a fallback-consensus of just trusted, super-stable dirrectory mirrors. Currently, it appears as if this fallback-consnsus must actually be signed by the authorities before it will be used for this (or any other) purpose. We should figure out a way to work with this, or around it.

This is not just for this case of censorship, but also for #2655 and DoS resistance.

And by #2655, I of course mean #2665 (and the parent, #2664) if that wasn't obvious. Good thing trac comments are readonly. What would we do without that feature?

We already have the notion of a fallback consensus. But see comment 9 of #572 for why we're not using it currently.

See #572 for the answer to this issue, and why we haven't done it yet. I agree we should do it.
