Sites moved. Nobody noticed.

Zero-downtime hosting & DNS migrations

Web infrastructure1 engineerMultiple properties

The problem

Business sites sat on aging hosting with manual deploys, no CDN discipline, and DNS spread across registrars — every change was a small risk to uptime and email.

The system

Static builds moved to Cloudflare Pages with git-driven deploys, DNS consolidated with explicit TTL and cache plans, apex/root constraints handled per registrar, and mail records preserved so email never blinks during cutover.

How it's built

Delivery

Executed per-site in hours, not weekends, with a rollback path at every step.

Results

Client anonymized by industry. Detailed numbers and references available on a call.
