Outages happen—no matter the hyperscale provider, no matter the architecture. What separates resilient organizations from the rest is how quickly they detect issues, how effectively they communicate, and how well they learn from the inevitable. I had the opportunity to co-present a session on the topic of how Microsoft communicates during outages and what YOU can do to be more proactive on how your Azure based infra is weathering the storm. Tajinder Pal Singh Ahluwalia and I pulled back the curtain on how Microsoft handles major incidents—from the first customer impact signal to the deep‑dive retrospectives that follow. Our session, “Anatomy of an outage and evolving our culture towards transparency,” was an updated version of a popular session from previous Microsoft Ignites that offered crucial lessons for infrastructure teams everywhere.
The Five Pillars of Transparent Outage Communication
Azure’s communications framework is built on five principles: speed, accuracy, discoverability, parity, and transparency. These pillars guide every notification and public update during an incident. As Tajinder emphasized, transparency isn’t a PR stance—it’s the backbone of operational maturity. Customers deserve to know what failed, why it failed, and how they can prevent similar issues in their environments.
A key enabler is Azure’s AI‑driven AIOps engine, Brain, an internal tool which automates initial incident notifications. Today, 90% of Azure services deliver alerts within 10 minutes, with the remainder guaranteed within 60. Speed is not optional at hyperscale. It’s table stakes.
Why Azure Service Health Should Be Non‑Negotiable
Shockingly, only 20–30% of Azure subscriptions actively use Azure Service Health—yet it’s the single most important tool for understanding how outages affect your specific workloads. Rather than relying on generic “is Azure down?” websites, Service Health gives you:
- Tailored incident visibility
- Granular scoping across subscriptions, resource groups, and services
- Historical alerting and automation hooks
- Integration points for SMS, Teams, webhooks, logic apps, and more

What to expect: Three stages of an incident - Before, During, and After an Outage
Before: Strengthen Your Signals
We recommend layering multiple monitoring sources:
- Azure Service Health for platform issues
- Azure Resource Health for per‑resource diagnostics
- Scheduled Events for planned maintenance
- Azure Monitor for performance and dependency telemetry
This is also where architectural resiliency comes into play—availability zones, VM scale sets, redundancy options, ASR, and backup. Not every workload needs every capability, but every critical workload needs intentional design.

During: Communicating at Cloud Scale
When incidents hit, Azure focuses on scale, equity, and signal clarity. Everyone—from the smallest tenant to Fortune 50 companies—receives the same information at the same time. Support tickets aren’t required for SLA credit; they're reserved for cases where the symptoms don’t match published impact.

(Don’t forget – Azure Service Health alerts always arrive faster so use both.)

After: Learning Without Blame
Post‑incident reviews (PIRs) are published within:
- 3 days for major incidents
- 14 days for smaller multi‑service events
These reviews have evolved into narrative, timeline‑driven analyses—focused not on blaming a “root cause,” but on mapping cascading dependencies and mitigation actions. Azure also hosts Azure Incident Response (AIR) livestreams featuring engineering leads talking through exactly what happened.

Final Thoughts
Infrastructure reliability isn’t just about designing resilient systems—it’s about understanding how your cloud provider detects, communicates, mitigates, and learns from failures. Azure’s maturing transparency culture, combined with tools like Azure Service Health and robust post‑incident processes, gives infrastructure teams the clarity they need to make informed operational decisions.
If there’s one takeaway, it’s this: GO CONFIGURE Azure Service Health today, and ensure the right people in your organization get the right signals at the right time. The next outage will happen. The question is whether you’ll be ready for it.
