Signal, the secure communications application created by Moxie
Marlinspike, has added another tool to its kit to evade Governments
that want to block their subjects from using it: “domain fronting”. The
technique requires routing through a content-delivery network, which
typically is not available for free. But it does mean the only way to
block the use of Signal is to block the user from the entire Internet.
At least for now.
