Comment (by cypherpunks):

 [https://www.theverge.com/2018/4/18/17253784/google-domain-fronting-
 discontinued-signal-tor-vpn A Google update just created a big problem for
 anti-censorship tools]

 > Reached by The Verge, Google said the changes were the result of a long-
 planned network update. “Domain fronting has never been a supported
 feature at Google,” a company representative said, “but until recently it
 worked because of a quirk of our software stack. We’re constantly evolving
 our network, and as part of a planned software update, domain fronting no
 longer works. We don’t have any plans to offer it as a feature.”
