I'm operating two Tor bridges. When calling bridges.torproject.org, for one of the bridges (set up in March, 2023), there are three outputs:
- obfs4: functional
- a bandwidth ratio
- a "last tested" entry.
But for my second bridge (set up at the beginning of June 2023), bridges.torproject.org does not output a bandwidth ratio.
What does this missing bandwidth ratio output mean, since everything else seems to be normal? When starting nyx on the relays, I see connections there (even more on the bridge with the missing bandwidth ratio output), I can connect to both bridges using the Bridge's IP addresses and ORPorts via Tor browser, and metrics.torproject.org also outputs an advertised bandwidth, which is even much higher (4.87 MiB/s at the moment) than for my other bridge (1.43MiB/s at the momemt) for which bridges.torproject.org outputs a bandwidth ratio.
The bridges run on virtual servers at the same hoster, but in two different countries. Nothing else runs on these virtual servers.
I am honestly not quite sure to what extent the fingerprint of the bridge is information worth protecting, or whether only the port and IP address need to be protected.
By the way, I also don't understand why my two bridges don't have a higher advertised bandwidth - currently, it's 4.87MiB/s for one and 1.43MiB/s for the other relay. I never got the fast flag for either bridge yet, in contrast to my two "normal" relays. On both servers, at least 1.6GiB/s is available, and a monthly data throughput of several terabytes.
As a further issue, nyx doesn't output (in constrast to my two other relays) - not sure if this is a known issue.
And, as a last issue, I didn't specify a distribution mechanism for my bridge, in the hope that the most suitable mechanism will be selected automatically. Initially, for one of my bridges (the one for which bridges.torproject.org outputs a bandwidth ratio) the bridge was assigned distribution mechanism "Moat". But suddenly, "None" is displayed under distribution mechanisms at metrics.torproject.org, which means that apparently the bridge is no longer distributed. What could be the reason that the distribution mechanism suddenly changed?
