FAQ

DNS Support FAQ

Common questions before starting fixed-scope infrastructure, automation or support work.

Can you troubleshoot production web stack issues?

Yes. We investigate web server, reverse proxy, SSL/TLS, cache, upstream, DNS and application runtime problems affecting live websites and services.

What details should we send for faster diagnosis?

Useful details include domain, nameservers and records involved, expected destination and current broken behaviour, TTL and planned cutover timing, plus when the issue started.

Can you help with 502 errors, redirects or SSL problems?

Yes. We can trace issues across the web server, upstream services, PHP-FPM, DNS, certificates, Cloudflare and application configuration.

Do you check rollback and downtime risk?

Yes. For production systems we confirm access, backups and change risk before making disruptive configuration changes.

How much does this work usually cost?

DNS and cutover support may start from $299 for small well-defined tasks, with larger migration work quoted separately.

After the fix

Reduce the chance of the same issue returning.

After a fixed-scope issue is resolved, we can also help with monitoring, backups, restore testing, security hardening or ongoing infrastructure support where it makes sense.
