I run two lower bandwidth middle relays, and have been considering changing one to a bridge to provide for a different level and type of users. It sounds like this may only be a temporary bump in the system, so I will continue with my thinking. Surprising to see some of the recent changes, we never know what tomorrow brings.

So what are we going to do when Green shuts down the Bridge Authority server next month? Will it have a serious effect, or will there be any apparent issues or slowdowns?


        

        
We'll have to act before that. We're currently looking for
a new operator for the bridge authority and a suitable hosting
location, which we will want to include in Tor releases asap.
For a while we will feed the data from the two concurrently
running bridge authorities to the bridge database for
distribution to users, then when Tonga (Lucky's auth) is shut
down the new one will have taken over. We will lose the data
about all bridges that aren't updated after the time Tonga is
shut off. This means fewer bridges for bridge db to give out and
potentially a drop in counted (not necessarily actual) bridge
users of Tor.


      

      
Old bridges will continue to function after the old authority is shut down, regardless of whether they are updated to the new Tor release. So existing users of those bridges will be ok.

Old bridges won't be able to send their details to the new bridge authority. So a Tor update is required on bridges, so they send their details to the new bridge authority. Then they can be given out to users.

Also, old Tor clients won't be able to get updated bridge descriptors from the new authority, but as far as I know, bridge descriptor updates aren't essential for clients to continue to use a bridge. (I may be wrong about this.)
