Have there been cases where snowflake bridges stopped receiving traffic from a specific country that blocked their IP’s? Like is there the same risk that your IP will get blacklisted in some country like with obfs4 bridges?
Here is my opinion. In theory they could but what a job that would be. I’ve been running a Snowflake proxy for about 7 months and in that time my IP has changed about 8 times. From what I read there are few thousand Snowflake proxies running and how many change IP like mine. It’s a residential connection.
I could just reboot my modem and that block is useless. I don’t think it would be a practical thing to implement.
snowflake.torproject.org says that there are
127,599 snowflakes right now, that’s a lot. 
But what if I have a Static IP? It’s interesting to me how censors will try to block snowflake if it’s designed so robust against censorship, with the brokers and webrtc and stuff…

China blocked Snowflake proxies in 2019, see Snowflake, a censorship circumvention system using temporary WebRTC proxies :
the cause was blocking of the IP address of the few proxies that existed at the time
As of now I am not aware of this happening, but it could very well be. Especially that the pool of unrestricted proxies is small, around 2700 (see metrics, snowflake-ips-nat-unrestricted).
Yes 127,599 is a lot. If I remember right, most of those are the browser extension types which I did try in the beginning. They service only 1 client at a time. Hardly worth the time and effort of these state actors who I will call agents 000 with their license to kill [any IP].
You have a static IP so, yes, you could become a target. A bit of monitoring would ID the IPs in question. Still the question: is it worth it for agent 000.
Then how would you ID Snowflake traffic? All UDP and to an IP in a country where there is no law against censorship circumvention. Could it be something else?? I don’t have the knowledge about what kind of traffic is all UDP.
Since running unrestricted (2024/11/23) my top clients are (as of 1 month ago): 12078 RU, 8541 IR, 970 US, 925 CN so China is not blocking my IP but then I am NOT static. A correction from above. My IP has changed 14 times since I started Snowflaking.
I suspect that the US stat is probably connections from a data center or something which someone is keeping open but don’t know that for a fact.
