• Some users have not experienced weekly or monthly outages with Azure and Microsoft services, contradicting claims of frequent downtime.
• The outage is affecting not only the Azure portal but also other Microsoft services, such as Intune, Entra, and login.microsoftonline.com.
• The differential impact of the outage across different tenants and geographies suggests a complex issue with variable effects.
• The lack of transparency and timely updates from Microsoft undermines confidence in their status page and services.
