Sudden drop in traffic on Tor Bridge - on a list?

Hi All,

I operate a Tor Bridge on a VPS in Europe. It uses obsf4 on port 443, and is distributed via HTTPS.

Normally, for the past several months, the metrics website reported ~30-35 active clients. I’d check the connections, and they were mostly from Russia and China.

However I’ve seen a sudden drop, now with just ~10 clients at a time, and mostly from US / countries with fairly open internet.

I wonder if my bridge somehow got identified and reported as such, so that many countries blocked it completely? (As in just block the IP for it). Any way I can test this theory?

Here is the metrics page if it is of interest: Relay Search
