Facebook’s offical .onion domain

Facebook announced that they have an offical .onion domain: https://facebookcorewwwi.onion/

What’s interesting is that their .onion is serving SSL and the SSL certificate’s SNAs list the .onion so that Tor Browser doesn’t complain about an invalid cert.

There was a discussion about just that on the CA/Browser Forum two weeks earlier, started by an DigiCert employee. Unsuprisingly Facebook’s certificate is issued by DigiCert.
