It seems to be working ok for me right now for both HTTP and HTTPS, although wfe0.ysv.FreeBSD.org seems to be non-compliant with RFC 7234 § 220.127.116.11 and § 18.104.22.168, by serving an aged response to a Cache-Control: max-age=0, no-cache request.
I'd also say, IMHO, the subject line should have been more descriptive. If in a hurry that's the type of subject line I'd ignore. A subject of freebsd.org. down? would have gotten far more people checking, and let people know there might be a problem.
