What is the safest way to roll out September updates on Azure Front Door without risking peak-hour outages?

To proactively detect latency spikes on Azure Front Door (AFD) before customers notice, SREs should monitor a comprehensive dashboard in Azure Monitor that focuses on both edge and backend performance. The dashboard should combine AFD metrics with Application Insights and network health data to differentiate between problems with the AFD platform, backend services, or the broader internet.

• AFD metrics dashboard

This dashboard uses platform metrics collected by Azure Monitor to give a real-time view of AFD's performance. 

• Application performance dashboard

This dashboard uses Application Insights to provide an end-to-end view of your application, validating if the issue is with your backend services rather than AFD.

• Network and multi-region dashboard

Since AFD performance is tied to its global network, monitoring broader network health is crucial.

• Automation for proactive alerts

To catch latency spikes before customers do, configure Azure Monitor alerts on these dashboard metrics.

In light of recent, complex outages like the Cloudflare-AWS congestion and Azure Front Door (AFD) platform configuration errors, disaster recovery (DR) testing for AFD must move beyond simple backend failures. Your tests should now simulate broader network degradations and AFD platform-level issues to validate your full resilience strategy. 

• 1. Test backend failover under duress
• 2. Simulate AFD platform-level failure
• 3. Verify end-to-end resilience during a game day
• 4. Practice communication and documentation

The Azure Front Door service is inherently resilient to regional cable cuts because it operates as a global entry point on Microsoft's backbone network. For added protection for workloads, you should combine Front Door's native multi-regional routing with multi-region application deployment and a DNS-based failover service like Azure Traffic Manager for extra redundancy.

To spot Amazon Bedrock latency spikes before they impact customers, SREs should focus on a multi-layered dashboard in Amazon CloudWatch. This approach uses Bedrock's native metrics, application performance data, and network-level insights to provide early warnings and help pinpoint the root cause of performance degradation.

"Recent Bedrock incidents, including model-specific routing errors (Anthropic) and external network congestion (Cloudflare-AWS), highlight that DR testing must go beyond simple regional failovers. Testing should now focus on simulating more granular, nuanced failures to validate the application's true resilience.
Here is an updated approach to testing disaster recovery for services on Amazon Bedrock:

• Validate application behavior during regional degradation
• Isolate and test model-specific issues
• Conduct multi-regional failover (Game Day)
• Test network isolation and security
• Document and automate the process"
