Yahoo! OpenID: Cinco de Mayo Outage

For anyone using OpenID, we wanted to let you know that on the morning of May 5th, the Yahoo! OpenID service experienced a partial outage that affected users and some of our OpenID Relying Parties. We learned about the outage through our YOpenID Twitter channel. Folks affected by the outage were unable to make HTTPS connections to the OpenID service, preventing users from signing in with their Yahoo! OpenID. We were able to restore service by 11am PDT.

In the spirit of openness and transparency, we wanted to let you know about the problem and thank those those who tweeted about it. The Yahoo! OpenID team takes uptime and site reliability very seriously, and we're adding additional monitoring to ensure that this type of outage does not happen again.

Thanks for using OpenID!
