teor:
Colin also asked relay operators to opt-in as fallback directory mirrors (in the last half of 2018). In December, he helped rebuild the fallback directory mirror list.
Thank you for working on this.
The fallback directory mirrors are being checked daily by the OONI probe TCP connect test that runs by default from many probes around the world. It currently tests the TCP connectivity (successful connection: true/false) of the directory authorities and bridges.
This list lives on the ooni-resources repository [1] it will be really neat if one can drop a notification or open a ticket so that this list gets updated.
Thanks!
