Hi,

I'm getting an error while trying to open an existing Trac ticket:

https://svn.boost.org/trac/boost/ticket/11798

Secure Connection Failed

An error occurred during a connection to svn.boost.org. Peer’s 
Certificate has been revoked. Error code: SEC_ERROR_REVOKED_CERTIFICATE

Is this a known problem?

Firefox 51.0.1.
