DNS
Does the domain resolve to a public address?
Pixeldust incident desk
Run a free public scan to see the most likely cause. We inspect DNS, HTTPS, server responses, returned page code, and sampled resources—then show what we actually observed.
Public scan in progress
Checking whether the hostname points to a public web server.
Surface scan complete
We rank probable causes from the evidence available publicly. The top result is not a confirmed root cause until the site and hosting environment are reviewed.
Each layer uses observed or measured public evidence.
Likelihood is based on the strength of the public evidence, not access to private logs.
We will review the failure, request only the access actually needed, confirm what broke, and explain the safest repair path before billable work begins.
Useful first evidence
The scanner can narrow the problem quickly, but it cannot see the private systems where the root cause often lives.
Does the domain resolve to a public address?
Can a secure connection and redirect path complete?
What status, timing, and infrastructure headers return?
Does the public response contain a recognizable failure signature?
Are sampled scripts, styles, and images available?
Why the review matters
A 503 can come from an application crash, overloaded hosting, maintenance mode, a failed deployment, or the CDN giving up on the origin. Public evidence can rank those possibilities. Logs and access confirm which one actually happened.
The free review bridges that gap. We diagnose first, then recommend the smallest responsible fix.
