UPDATE: Storing Microsoft Multi-Factor-Authenticatie verholpen
Een aantal van onze en andere Microsoft klanten (in USA, Europa en Azië) die gebruik maken van Multi-Factor Authenticatie heeft last van een storing bij Microsoft waardoor er niet met MFA kan worden ingelogd.
Dit betekent dat je mogelijk niet op Office 365, Azure, andere Microsoft Clouddiensten of gekoppelde diensten die gebruik maken van MFA kunt inloggen.
Wij houden je via updates op dit bericht op de hoogte van de actuele status.
2fa probleem opgelost: Multi-Factor Authentication – Mitigated
Summary of impact: Between 14:25 UTC and 17:08 UTC on 27 Nov 2018, customers using Multi-Factor Authentication (MFA) may have experienced intermittent issues signing into Azure resources, such as Azure Active Directory, when MFA is required by policy. Impacted customers may have encountered timeout errors.
Preliminary root cause: After a preliminary investigation, engineers found that an earlier DNS issue triggered a large number of sign-in requests to fail, which resulted in backend infrastructure becoming unhealthy.
Mitigation: After the DNS issue was resolved, engineers then focused on cycling the relevant backend services to resolve the congestion issue. They observed a decrease in the failure rate after the reboot cycles.
Next steps: Engineers continue to monitor overall platform health and prevent future occurrences. A full Root Cause Analysis (RCA) will be made available within 72 hours
CURRENT STATUS: Engineers found that an earlier DNS issue had resulted in failures for a large volume of sign-in requests. This DNS issue has been mitigated. Engineers are recycling all backend services to provide temporary mitigation, and we continue to work on full recovery
Title: Unable to access Microsoft 365 services User Impact: Users may be unable to sign in to Microsoft 365 services using Multi-Factor Authorization (MFA).
Current status: We’ve determined that a Domain Name System (DNS) issue caused the sign-in requests to fail. We’ve mitigated the DNS issue and are restarting the authentication infrastructure for the remediation to take effect. Scope of impact: This issue may potentially affect any of your users attempting to sign in using MFA. Start time: Tuesday, November 27, 2018, at 2:25 PM UTC Preliminary root cause: A Domain Name System (DNS) issue caused the sign-in requests to fail, resulting in impact to the service.
