TL;DR: DNS locality can improve user experience by cutting response times, improving routing efficiency, and strengthening resilience against DNS hijacking and DDoS pressure, according to DigiCert. The security implication is that it does not replace governance over DNS integrity, availability, and failure handling.
NHIMG editorial — based on content published by DigiCert: Boosting Internet Performance in Mumbai, India: Unleashing the Power of DigiCert DNS PoP
By the numbers:
- Mumbai, India is described as a city with a population of over 20 million people.
Questions worth separating out
Q: How should security teams govern DNS for identity-critical services?
A: Treat DNS as part of the trust path for authentication, certificate validation, and workload access.
Q: Why does DNS locality matter for IAM and workload identity programmes?
A: DNS locality matters because identity systems depend on resolution for reaching login services, certificate endpoints, and machine-to-machine APIs.
Q: What breaks when DNS performance is improved without security controls?
A: Faster DNS alone does not prevent hijacking, malicious redirection, or service disruption.
Practitioner guidance
- Map DNS dependencies in identity-critical services Identify which authentication, certificate validation, and application access flows depend on DNS resolution latency.
- Monitor resolution integrity and availability together Track response time, NXDOMAIN spikes, TTL behaviour, and unexpected routing changes in the same operational view.
- Test failover from the user’s geography Run regional failover exercises from the locations where users and workloads actually operate, not only from central infrastructure.
What's in the full article
DigiCert's full blog covers the operational detail this post intentionally leaves in the source:
- The article describes the Mumbai DNS point of presence in the context of local performance gains and service responsiveness.
- It expands on the security claims around DNS hijacking and DDoS resistance that were only summarised here.
- It frames DigiCert's network routing and support model for readers who need vendor-specific service context.
- It provides the source's own explanation of why Indian users and businesses are targeted by the Mumbai deployment.

DNS locality is a trust and availability decision, not just a performance tweak. The article frames the Mumbai point of presence as a speed improvement, but the deeper governance issue is that DNS placement changes the operational boundary of name resolution. For identity and access programmes, that affects certificate validation flows, workload reachability, and the reliability of dependent services. Practitioners should treat DNS architecture as part of the trust stack, not a standalone network optimisation.
A few things that frame the scale:
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to The State of Secrets in AppSec.
- Only 44% of developers are reported to follow security best practices for secrets management, according to The State of Secrets in AppSec.
A question worth separating out:
Q: How do teams decide whether a regional DNS point of presence is worth it?
A: Teams should compare the latency gain against the operational complexity it introduces, including new failure paths, monitoring needs, and regional dependency changes. If the services involved are identity-critical or customer-facing, the bar should include both user experience and resilience under attack or outage conditions.
