The github mirror of FreeBSD's svn-git gateway (https://github.com/freebsd/freebsd) is delayed by over four hours. The most recent svn head revision to make it to the git mirror is r307731 with a timestamp of Fri Oct 21 15:23:54 2016 +0000. This was presumably broken by Dyn's DNS DDoS outage. The issue is currently under investigation.
