SSL certificate errors October 13, 2016 (resolved)
We’re receiving reports that some people visiting some SSL sites (including our site) are seeing security errors saying a “certificate has been revoked”.
This is an Internet-wide problem caused by an issue with one of the main Internet “certificate issuers”, a company called GlobalSign, and isn’t specific to us or sites we host. It’s affected many large Internet sites, such as Wikipedia. (Internet news site “The Register” has a report here.)
GlobalSign says the problem will soon be fixed. In the meantime, if your browser allows you to “click past” the warning about a “revoked certificate”, it is safe to do so.
Update 3:13 PM Pacific time: The problem is slowly resolving itself as the bad certificate information expires from “caches” around the Internet, but we’ve temporarily replaced our SSL certificates with new ones to make it stop immediately. This problem should now be resolved.
