Office 365 Users Unable to Log On with Multi-Factor Authentication


At approximately 9:30 PM CDT on October 18, 2018, Office 365 Multi-Factor Authentication services went down preventing users with this vital security service from being able to sign on. Microsoft reports that they are investigating the issue updates published hourly at the Office 365 Service Health Status.

Nothing has been publicized by main-stream media as of yet. A similar incident occurred on November 18, 2018 due to implementing an update and a hotfix was released to correct but took nearly 4 hours.

As streamlining technology is about avoiding risks, we purposefully don’t implemented updates or changes over a weekend or holiday so revenues aren’t lost and users don’t go looking for pitchforks and torches.
