An anonymous reader writes: Microsoft, just like Google, Apple, and Mozilla, is part of the CA/BForum, an organization of web browser vendors and certification authorities (CAs). As a browser vendor, Microsoft maintains a list of authorized CAs and their respective root certificates. According to a message on the CA/BForum, there was an error on the server that was running a CRM application that managed this list of trusted certificates and the adjacent details regarding each certificate and CA. The data is lost forever and Microsoft is now asking CAs to resend their most recent audits. Currently a lot of certs are broken in Edge and IE. Microsoft says that it lost audit data for 147 root certificates, which resulted in many SSL/TLS certificates showing errors inside the company's products.
