Thousands Of Secure Websites Dubbed Insecure Due To Cert Error

A maintenance exercise gone awry at root certificate authority GlobalSign caused what could be thousands of websites to be mistakenly treated as insecure by web browsers and therefore become inaccessible to users attempting to reach them.

GlobalSign itself has resolved the issue at its end. But users who visited the affected sites before the problem was resolved could find themselves being blocked until their browser cache expires—a process that could take four or more days.
