    66 * obfs2 isn't blocked; kzblocked speculates it's because the initial packet is too short to get a good entropy estimate.
    77 * The blocking of vanilla started on June 2. Bridges were somehow lagged or degraded so people gradually stopped using them.
    8  * Behavior differs across ISPs. Someone said that in one case it's a Fortinet FortiGuard firewall.

    1010kzblocked wrote a Windows program that allows obfs4 connections to succeed, by shrinking the server's TCP window so the client's first packet is smaller.
