Correct me if I'm wrong: Telegram has been blocked in China mainland. So if normal Chinese botnets want to DDOS Telegram, they will be blocked by GFW first. So how these botnets succeeded? Does that mean they are "special"?

GFW has many ways of blocking things, I would assume that they just aren't blocking all traffic to telegram IPs.

  Pretty sure they are.

    Are they actually blocking outgoing packets to the IPs or injecting RSTs or blocking incoming packets from those IPs? I don't have a Chinese connection to test from right now.

      My understanding is that it's a heterogeneous system that does different things for different people at different times. Looks like Wikipedia has some technical details- https://en.wikipedia.org/wiki/Great_Firewall#Blocking_methods https://en.wikipedia.org/wiki/Great_Firewall#Blocking_method...
