On October 9th, 2025 several TrioAir customers experienced problems with their system. The cause of this problem was a breakdown in the Microsoft Azure cloud system. While TrioAir is based on Microsoft Azure, there was no issue with the TrioAir system itself. To summarize Microsoft’s response to the problem:
“Some Microsoft Azure customers had trouble connecting to their services — things were slow or sometimes didn’t load at all. This problem affected users around the world.
The issue happened because part of Microsoft’s system (called Azure Front Door) temporarily lost about one-third of its capacity when some of its background computers crashed”.
Customers wanting more detailed information can read the Microsoft statement:
“Starting at 07:40 UTC on 09 October 2025, Microsoft Azure customers using Azure Front Door (AFD) may experience intermittent delays or timeouts when accessing their services. This includes the ability to access the Microsoft Azure Portal and leverage Microsoft Entra.
Our monitoring detected a significant capacity loss of about 30% of Azure Front Door instances, predominantly across Europe, Middle East, and Africa. We understand that this is due to a dependency on some underlying Kubernetes instances that crashed.
We have ruled out any deployments that could have triggered this event.
We have been restarting these underlying Kubernetes instances, and AFD instances are coming back online. Customers should start seeing recovery as we bring these instances back online, and we expect full mitigation within the next 90 minutes.
The next update will be provided within 60 minutes”.
