Twitter user Tzatl tweeted at the company on Sunday, asking: Did you guys really forget to renew a certificate? Microsoft responded that it had isolated the problem and was applying a fix, referring users to entry EX257883 under its service health dashboard.
The issue provoked some teasing from users on Twitter. Someone done goofed, replied one user, along with a picture of the untrusted certificate report from Digicert Cloud Services.
This isn t the first time a large technology company has downed a service by forgetting to renew a certificate.
