How can i find out my OBFS4 bridge or Snowflake is blocked by a censor country?

What are ideas on how to find out my bridge/OBFS/Snowflake is blocked in Iran/China/Russia or similar censor country? Ideally some way so i can automate the check maybe using bash script or be email notified.

Once I am blocked, maybe then is the time to move from bridge to middle relay?

Have a look in the stats folder which is written every 24 hrs, if the said countries drop out from the stats then you know. same for snowflake/obfs/webtunnel,

This is one of my webtunnel bridge stats
