HTTPS available
Methodology v7 · canonical ID https-available · TLS & Certificates · scored · census as of July 28, 2026
Without it, browsers warn visitors "Not secure" and they leave.
Definition
| Canonical ID | https-available |
|---|---|
| Category | TLS & Certificates |
| Grade impact | Scored — counts toward the grade |
| Pass | The site serves content over HTTPS (TLS handshake completes and a response is returned). |
| Fail | The site is reachable over plain HTTP only, or HTTPS connections fail. |
| Example (passing) | https://example.com/ → HTTP 200 over TLS |
No-data rule: when this check couldn't be determined for a domain (timeout, SERVFAIL, redacted
source) it returns N/A and is excluded from that domain's scoring denominator — "couldn't determine"
is never counted as a failure. "Determined absent" is a real fail.
Prevalence across the census
76.3% of graded domains serve over HTTPS (210,439,319 of 275,666,275, as of July 28, 2026).
Census denominator: 275,666,275 graded domains. Aggregates only — never an individual domain's result.
