DNS Debugging Service
Authoritative DNS failures diagnosed fast: propagation, delegation, DNSSEC, and stealth misconfigurations.
DNS breaks everything at once and explains nothing: mail bouncing, sites unreachable in some regions, renewals failing, subdomains vanishing after 'harmless' changes. Our DNS debugging traces delegation chains, glue, DNSSEC validation, and propagation from multiple vantage points, and fixes the actual fault instead of waiting 48 hours and hoping.
At a glance
- Multi-location resolution testing
- Delegation, glue & DNSSEC tracing
- Propagation verified, not assumed
- Minimal fix with root-cause report
- Prevention checklist included
What we diagnose
Broken delegation and missing glue at registrars; lame nameservers answering inconsistently; DNSSEC chain-of-trust failures and expired signatures; conflicting records and stale caches; split-horizon and view misconfigurations; TTL traps that turn small edits into long outages.
How a debug engagement runs
External resolution tests from five geographies, delegation tracing from the root, DNSSEC validation step by step, zone-file audit against live answers, then the minimal fix, verified propagation, and a written explanation of cause plus prevention.
Frequently asked questions
How long does DNS debugging take?
Most faults are identified within the hour; complex delegation/DNSSEC chains can take a day including propagation verification.
Can you fix it without breaking mail?
Yes, mail records get explicit pre-change snapshots and post-change flow tests on every engagement.
