Microsoft Office 365 had an outage on Friday which left users without email throughout Europe, the US and the Asia-Pacific. Microsoft users who tried to access their accounts on Friday got the message “Service is temporarily unavailable. Please retry later.” UK users were hit hard with one user complaining that they could send or receive emails for over 14 hours.
Microsoft themselves acknowledged the service outage via Twitter, saying, “Hi. Today we’re investigating reports of our dear customers having issues with logging in to Microsoft Account/Office 365. Our Network Operation Centre Engineers are currently working to resolve this. More details will be provided shortly.”
Later, it reported, "We've completed all recovery actions related to MO133518 and this issue is fully resolved as of Friday, April 6, 2018, at 11:30 AM UTC. Thanks to everyone who confirmed service restoration." Also, Microsoft’s Azure Active Directory, cloud-based service, was reportedly down for users worldwide, until it was restored.
The latest Microsoft Office 365 outage once again reminds organisations about the dangers of relying on a single vendor for critical corporate infrastructure. Many of Topsec’s customer who wrap Topsec Email Security around Microsoft Office 365 to provide extra layers of security against spam, malware, ransomware and phishing were able to logon to Topsec Email Continuity to ensure email availability and maintain business as usual.
