Hi,

I don't know if the discussion of the thread "22% of bridges run by a single entity?" [1] sparked this, but someone was very busy adding lots of obfs4 bridges.

Normally you would see <50 new bridges per day, in the last few days we saw >120 new bridges per day.

They all run tor 0.2.9.10, support the obfs4 transport and have a nickname that looks like it is generated from a dictionary.

You can even see it on metrics: https://metrics.torproject.org/networksize.html
