There is increased usage of the snowflake-01 bridge since yesterday, likely related to protests/shutdowns in Iran. The 4 load-balanced tor instances, which recently were at about 60% CPU at the steady state, are currently near 100%.
I am planning to increase the number of instances today.
I am also seeing a lot of "no address in clientID-to-IP map (capacity 10240)" (dozens per second), so I will increase that parameter at the same time.
After this, I don't think this bridge can easily sustain another doubling in traffic. It would be good to start sharing load with snowflake-02 sooner than later (https://bugs.torproject.org/tpo/anti-censorship/pluggable-transports/snowfla...).
Here's a bridge-extra-info from a couple of days ago. (Remember this represents 1/4 of traffic.) Here `ir` is in about tenth place in users.
