Here's some numbers. total bridges: 4323 total bridges with PTs: 1867 total obfs4: 1413 (obfs2 or obfs3): 1739 (obfs2 or obfs3) and (not obfs4): 438 (obfs2 or obfs3) and (obfs4): 1301 obfs4 only (no other transports): 112 -- ââ isis agora lovecruft _________________________________________________________ OpenPGP: 4096R/0A6A58A14B5946ABDE18E207A3ADB67A2CDB8B35 Current Keys: https://blog.patternsinthevoid.net/isis.txt
