Cloud DNS 101: What Most Teams Get Wrong About Authoritative DNS
Most teams treat DNS as a one-time setup, until downtime proves otherwise. This webinar explains why registrar DNS is a liability at production scale, and how authoritative DNS with Anycast routing changes the availability equation entirely. VergeCloud engineers Dhiraj Chaudhary and Arsath Parves cover the full DNS hierarchy, geo-proximity traffic steering, and DNSSEC as a defence against cache poisoning and volumetric DNS attacks.

How to detect DNS flood attacks?
Systems use historical context, baseline comparisons, and intelligent algorithms to flag malicious query volume.
What is the difference between registrar DNS and authoritative DNS?
Registrar DNS is a basic service bundled with domain purchases. Authoritative DNS is purpose-built with Anycast routing, TTL control, and SLA-backed uptime. The distinction is critical for production-grade availability.
Can DNS configuration affect SEO rankings?
Yes. Slow DNS resolution adds to Time to First Byte (TTFB), which search engines factor into page ranking. Faster authoritative DNS directly improves perceived performance.
How does DNSSEC protect against cache poisoning?
DNSSEC adds cryptographic signatures to DNS records, ensuring resolvers can verify that responses come from a legitimate authoritative server and have not been tampered with.
Is VergeCloud's DNS infrastructure built for Indian traffic?
Yes. VergeCloud operates authoritative DNS nodes across multiple Indian PoPs, ensuring fast resolution times for the majority of Indian internet traffic.

Indian websites face four times the global average in cyberattacks, yet most teams still assume their cloud provider handles application layer security. This webinar examines the real threat landscape for Indian businesses, drawing from major 2024 data breaches at Boat, Star Health, and BSNL. VergeCloud Solutions Engineer Arsath Parves covers WAF, API security, DDoS mitigation, and bot filtering, and walks you through a practical origin lockdown checklist you can act on right away.
