DNS issues can make a healthy site unreachable

A website can have a working server and still fail visitors if DNS resolution breaks. For customers, the result is simple: they cannot reach the site, a campaign page, a checkout route, or a login page.

NorthDuty includes DNS checks inside the same monitoring run that records HTTP status, SSL, redirects, response timing, blank-page detection, broken resources, JavaScript errors, and first-party API calls.

What DNS monitoring helps detect

DNS belongs in the same timeline as uptime and page health because it directly controls reachability.

Resolution failures

Detect when a domain fails to resolve correctly and visitors cannot reach the page.

Domain health context

Keep DNS and domain-related signals visible next to SSL, HTTP status, redirects, and page health.

Route-level monitoring

Monitor DNS impact on the pages that matter most to revenue, signups, support, and customer access.

Incident context

When a page is unreachable, see whether DNS, SSL, HTTP, or rendering signals are the likely source.

Why DNS monitoring matters

DNS failures are basic infrastructure problems, but their business impact is immediate.

Catch reachability problems that start before the page loads
Separate DNS problems from server, SSL, redirect, and rendering problems
Protect campaigns, checkout, signup, and account-access pages
Reduce guesswork during website reliability incidents
Keep domain health visible in the same workflow as customer-facing page health

How NorthDuty DNS monitoring works

DNS checks run with the rest of the website health monitoring signals.

1

Create a project with your domain

Add your base URL and NorthDuty starts checking whether the domain resolves correctly.

2

Run recurring health checks

Each monitoring run records DNS alongside HTTP, SSL, redirects, page rendering, JavaScript, and API signals.

3

Review the failure context

If a page becomes unreachable, the timeline helps show whether DNS is part of the problem.

4

Prioritize critical routes

Start with homepage, pricing, checkout, signup, login, and campaign pages where reachability matters most.
