GlobalSign security certificate foul-up knocks out secure websites
A security certificate mix-up has frozen hundreds of thousands of websites.
If you can’t get to some of your favorite websites today, it’s may not have a thing to do with your browser or ISP. The blame likely goes to GlobalSign, a Belgium-based security certificate provider. The company fouled up a clean-up of some of their root certificates links. This resulted in many “secure” websites showing up as being insecure and, depending on your web browser, unavailable.
