[tor-dev] Networks Blocking Tor's SSL Connections

Hi All,

This morning I observed a “free wifi” network blocking tor’s SSL connections. While other SSL connections from my machine went through, I observed multiple network traces of tor completing a TCP 3-way handshake, and then getting no reply to the first SSL packet it sent.

I think they may have been blocking unknown or untested certificates, but I can’t be sure.

Still, I was able to use meek(-google) to access tor.

Has anyone else seen this kind of blocking behaviour?
(Is this the right list?)
