Fallback directory mirror DFRI7 is dead

Hi teor, Fallback directory mirror DFRI7 [0] is down, due to multiple disk krashes, since about 30h and will not come alive with the same key. [0] 171.25.193.131:80 orport=443 id=79861CF8522FC637EF046F7688F5289E49D94576 A new DFRI7 will appear on the same address and port within a couple of days. Should I simply update fallback_dirs.inc?

No need to do anything right away! We do a fallback refresh every 6-12 months. The list is backported to 0.2.8 and later, and goes out in the next patch release. I've updated the ticket [1] we're using to track whitelist changes. There is also a master ticket [2] for the 0.3.2 or 0.3.3 fallback refresh. We try to keep 90% of fallbacks available, and we're currently at about 88% [3]. (The network can cope with 50% of the fallbacks being down, but it puts load on the authorities.) So we'll do a refresh [4] some time in the next few months. It would be great to get it done in September for the 0.3.2 alpha series [5]. If anyone wants to help generate the list, the instructions are at [4] in section 3b. (We wrote longer instructions, but they took a lot of time, without adding much value.)

Will it be bad to have a new relay (with a new key), on the same IP:port as what many clients think is an existing fallback relay? I can imagine clients getting warnings in their logs, about how they're getting an unexpected fingerprint while attempting to connect. --Roger

The new relay won't be eligible for the list until it's been up for at least a month. And it will take time to build up bandwidth weight. Since DFRI has a few eligible relays, we will probably choose different ones in the next list.

Since 0.2.8.5-rc, Tor logs an info-level message saying that we'll try another fallback: https://trac.torproject.org/projects/tor/ticket/18812#comment:8 T -- Tim Wilson-Brown (teor) teor2345 at gmail dot com PGP C855 6CED 5D90 A0C5 29F6 4D43 450C BA7F 968F 094B ricochet:ekmygaiu4rzgsk6n xmpp: teor at torproject dot org ------------------------------------------------------------------------
