 This issue was automatically migrated from github issue
 https://github.com/TheTorProject/ooni-probe/issues/182.

 In order for ooni-probes to discover collectors and test helper addresses
 ooni-probe uses a bouncer.

 The protocol for such system is specified here:
 https://github.com/TheTorProject/ooni-
 spec/blob/master/oonib.md#40-bouncer.

 Our idea for deploying this on m-lab is to have one unique Tor Hidden
 Service private key that is shared by all the m-lab instances running
 ooni-backend. This will provide load balancing given by the Tor Hidden
 Service protocol.

 It also allows us to have one unique .onion address that we can bake into
 the ooni-probe that will allow it to securely discover new collector and
 test helper addresses.

 From speaking with @stephen-soltesz and @meredithmeredith it appears that
 the m-lab platform currently lacks the ability to provision the machines
 with some private key material.

 This is a problem for us since to securely bootstrap the system we need to
 have a persistent address. This means that even if we were to generate the
 tor hidden service private key on the machines we would then not be able
 to distribute this address to the probes (because it would be changing
 over time).

 The ideal solution to this problem is to have support for provisioning of
 private key material to the ooni-probes.

 A temporary fix to this would be running the bouncer on a different system
 that is not m-lab and have this system fetch the list of collectors and
 test helpers via m-lab NS.

Comment:

 This is no longer needed as the bouncer will be deployed on a machine run
 by ooni.
