Microsoft Azure
Scope of impact
Starting at approximately 16:00 UTC, customers and Microsoft services leveraging Azure Front Door (AFD) may have experienced latencies, timeouts, and errors. We have confirmed that an inadvertent configuration change was the trigger event for this issue.
Updates
Latest (19:57 UTC): Microsoft initiated the deployment of their ‘last known good’ configuration, which has now successfully been completed.
Customers may have begun to see initial signs of recovery. Microsoft is currently recovering nodes and routing traffic through healthy nodes, and as they make progress in this workstream, customers will continue to see improvement.
Customer configuration changes will remain temporarily blocked while we continue mitigation efforts. We will notify customers once this block has been lifted.
Some customers may also have experienced issues accessing the Azure management portal. Microsoft has failed the portal away from AFD to mitigate these access issues. Customers should now be able to access the Azure portal directly, and while most portal extensions are functioning as expected, a small number of endpoints (e.g., Marketplace) may still experience intermittent loading problems.
At this stage, Microsoft anticipates full mitigation within the next four hours as they continue to recover nodes. This means they expect recovery to happen by 23:20 UTC on 29 October 2025. We will provide another update on their progress within two hours, or sooner if warranted.
Although we are seeing signs of recovery and have an estimated timeline, customers may also consider implementing existing failover strategies using Azure Traffic Manager to redirect traffic from Azure Front Door to their origin servers as an interim measure.
(18:24 UTC): Microsoft has initiated the deployment of their last known good configuration, which is expected to complete within 30 minutes. As this deployment progresses, customers should begin to see initial signs of recovery. Once completed, Microsoft will begin recovering nodes and routing traffic through these healthy nodes.
Customer configuration changes will remain temporarily blocked while we continue mitigation efforts. We will notify customers once this block has been lifted.

Microsoft does not yet have an ETA for full mitigation, but we will provide another update within 30 minutes, once the deployment has completed.

(12:07 PM CDT): We are waiting for Microsoft Health Dashboard to load, so we can update the incident number along with any additional updates.
