Website Health Report
DNS, SSL, HTTP and timing in one report.
Checked from our server. One location, so results show reachability from there only.
What the website health report does
The website health report runs a full set of checks on one address and puts the answers on a single page. It looks up the domain in DNS, opens a connection, reads the security certificate, requests the page, follows any redirects and reads the page title. It then reviews six security headers and pulls the domain’s name server, mail and email-authentication records.
It’s a good first stop when a site feels wrong but you don’t know where to look: after moving to a new host, before a launch, or when someone asks you to look over their website. It shows which layer has the problem, so you know which tool to open next.
How to use the website health report
- Type a website address.
- Press Run report. It takes a few seconds, because every layer is checked in turn.
- Read the verdict first, then each layer. Use the links at the bottom to dig deeper into DNS, certificates, speed or email.
Understanding the results
The verdict says whether the site is reachable from our server, has problems or isn’t reachable. Below it, each layer is marked OK, Warning or Problem. A certificate with 14 days or fewer left gets a warning, and so does a server that takes more than three seconds to start answering. If the site redirects, a table lists each hop with its status code and time. A 403 or 429 still counts as reachable: the server answered, it just turned away an automated request.
The security headers score counts how many of the six are present, from 0 to 6. X-Content-Type-Options only counts when it says nosniff, and a Content-Security-Policy with frame-ancestors stands in for X-Frame-Options. In the DNS and email section, an empty MX line means the domain doesn’t receive email, and no CAA record means any certificate authority may issue certificates for it. For a closer look at the email records, use the SPF and DMARC checker.
Questions
What do the security headers mean?
They are optional instructions that make browsers safer when visiting the site. Missing ones are advice, not a failure; each row explains what the header does.
Can I check one page rather than the home page?
Yes. Paste the full address and the HTTP, redirect and content checks run against that page. The DNS and mail records always belong to the domain.
How long does the server have to answer?
We allow three seconds to open a connection and eight seconds for a response. A server that takes longer is reported as not answering.
Does a good report mean the site is up for everyone?
No. Checks run from our server, in one location, so results show what that location sees. It tells you the site works from there.
Do you store the report?
No. The report is built for you and not saved. The Website Down Checker saves shareable results.
