Zero-Downtime Route 53 DNS Migration: SRE-Led Precision

Modernize your infrastructure starting with the foundation: DNS.

Migrating production DNS is often viewed as a "high-risk" event. Misconfigured TTLs or missing MX records can result in hours of downtime and lost revenue. This service provides a Senior SRE-led migration from any external registrar (GoDaddy, Cloudflare, Namecheap, etc.) to AWS Route 53.

We don't just "flip a switch." We apply SRE principles—observability, validation, and automation—to ensure a seamless transition. Every migration includes an audit of existing records, Infrastructure-as-Code (Terraform) preparation, and a phased cutover strategy that eliminates propagation lag issues.

Why choose this service?

• Zero-Downtime Methodology: We utilize pre-migration TTL lowering and serial-number validation.

• IaC-First: Receive your DNS records as clean, reusable Terraform code.

• Compliance-Focused: Delivered by a UK-based Senior SRE with no offshoring.

• Bilingual Expertise: Support available in English and Spanish for UK and EMEA operations.
