Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.
Domain and Registration
Registered in 2015, this domain has about 11 years of history. That suggests continuity, although ownership and purpose may have changed. The domain uses the common .nz extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by Amazon Route 53, indicating managed DNS hosting. The CNAME points to hadley.github.io, associated with GitHub Pages. No MX record was found. A conventional explicit inbound-mail route is not configured. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed. The lowest observed DNS TTL is 300 seconds.
TLS and Certificates
The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.
HTTP and Browser Security
The checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. CORS permits any origin to read this response. This is common for public resources; sensitive responses need narrower handling. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The x-cache, x-served-by, via response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers.
Technology Stack Analysis
The public page identifies bookdown 0.42 with bs4_book(), jQuery, Bootstrap, Google Analytics, Fastly without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The Generator tag identifies bookdown 0.42 with bs4_book(), making the publishing system easier to fingerprint. No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. Open Graph is partially configured; og:image is missing. Twitter Card metadata is configured. The title has 20 characters, within a common display range.
