Website Overview

Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.

Domain and Registration

Unknown

DNS and Email

The lowest TTL is 12 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Akamai Edge DNS, indicating managed DNS hosting. DNS and provider evidence indicate traffic passes through the Fastly CDN, which may support caching and traffic distribution. MX records point to the Microsoft 365 email service. The CNAME points to pantheon-systems.map.fastly.net, associated with Fastly.

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's total validity is about 29 days, consistent with a short renewal cycle. The certificate covers the main domain and its usual www hostname.

HTTP and Browser Security

The response lacks these common security headers: CSP, Referrer-Policy, Permissions-Policy. 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. The Server header identifies nginx without an exact version.

Technology Stack Analysis

The public page identifies Drupal 11 (https://www.drupal.org), Drupal, jQuery, Fastly, nginx without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

No homepage meta description was detected, leaving snippet selection more dependent on page text. The Generator tag identifies Drupal 11 (https://www.drupal.org), making the publishing system easier to fingerprint. Open Graph is partially configured; og:description, og:image, og:type is missing. The title has 37 characters, within a common display range. The observed directives allow indexing and link following.
