Monitor client DNS health before resolution problems become outages
DownCTL helps you see DNS failures, authoritative nameserver response evidence, and reputation issues beside the rest of each client website health story.
No credit card required during the trial period.
What DNS monitoring tracks
DNS monitoring checks resolution and reputation signals that can interrupt access even when the website and servers themselves are healthy.
DNS health
DNS record availability
A and AAAA resolution failures
Authoritative nameserver response checks
DNS blocklist status across major zones
Delisting context for listed zones
Related alert rules
Why it matters
DNS issues can masquerade as outages, reputation problems, or intermittent customer failures. Keeping DNS visible shortens investigations.
DNS issues can look like full outages
Authoritative nameservers can fail even when a cached resolver still has an answer
Blocklist problems can affect email and reputation
DNS evidence is easy to miss manually
How it works in DownCTL
DNS monitoring keeps configuration risk visible in the same operating view as uptime, domains, SSL, and reputation monitoring.
- 1 Add a site
- 2 DownCTL checks DNS health, nameserver responses, and blocklist signals
- 3 Review results alongside uptime and SSL
- 4 Use zone-level blacklist details when an IP is listed
- 5 Alert on failures or reputation issues
Keep exploring the website operations stack
DownCTL checks client websites continuously, records response history, and alerts your team when downtime or slow responses need attention.
DownCTL watches certificate validity, expiration windows, hostname coverage, and certificate evidence across client sites so your team can renew or investigate before visitors see browser trust warnings.
DownCTL tracks registration timing and RDAP evidence for client domains so renewal reminders, registrar details, and nameserver context do not disappear in inboxes, calendars, or ownership changes.
Create reusable destinations and workspace routes for early warnings, incidents, and daily digests — with clear delivery history for every channel.
