It appears all HTTPS/SSL tests that use the remote host svn.python.org are failing.

All branch builds (tests) are currently broken on koobs-freebsd-current. I think it's the only bot that has run builds post 24th December so far.

Investigation reveals:

svn.python.org uses an invalid security certificate. 

The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. 

The certificate expired on Friday, 25 December 2015 7:28 AM. The current time is Saturday, 26 December 2015 1:01 AM. 

(Error code: sec_error_unknown_issuer)
