to underline the relevance of this:
one of the most important IP blocks (185.222.100.0/22) on the internet with regards to Tor created route origin authorizations (ROAs) for their prefixes. These prefixes are use by 3 major exit operators (including the biggest exit operator).
they make up >15% of the Tor network's exit capacity, which means that we are around 50% RPKI ROA coverage for Tor exit capacity now.
