Comment (by dcf):

 Psiphon and Lantern both independently discovered this issue. They found
 that connecting with no SNI is necessary when using the
 [http://www.fastly.com/ Fastly] CDN. They both worked around it by
 patching the Go crypto/tls library.

 Psiphon:
  * Go http.Transport modified: no SNI in TSL client hello, new meek client
 binary\\

 Lantern:
  * Bad news - I had to fork Go's tls library.\\
