Having a backup doesn't automatically mean you have independent resilience.
Microsoft has confirmed a multi-region Azure networking incident affecting services including ExpressRoute, VPN Gateway, Azure Firewall, Application Gateway and Azure VMware Solution.
UK South and UK West were among the regions affected.
Microsoft says the problem was linked to a gateway-management change interacting with infrastructure servicing activity.
The incident has now been mitigated.
For businesses, the useful lesson isn't simply that Azure experienced an outage.
It's this:
Could your primary service and your backup be affected by the same underlying problem?
Ask:
• Do our connectivity paths share the same provider?
• Do they depend on the same region?
• Can the backup carry the real workload?
• Have we actually tested failover?
• Do we monitor both paths?
• What does the business do during degraded connectivity?
Redundancy isn't about having two things.
It's about making sure one can still work when the other fails.
If your organisation relies on Azure or hybrid infrastructure, HTL can help you review the resilience around your current environment.
