Website Overview

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

The lowest TTL is 34 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by umn.edu, indicating managed DNS hosting. MX records point to the umn.edu email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown.

TLS and Certificates

The public key uses EC with 256 bits. 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 response lacks these common security headers: CSP, Permissions-Policy. 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 cf-ray, x-cache, 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 Drupal 11 (https://www.drupal.org), Drupal, jQuery, Cloudflare without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

The meta description has 166 characters and may be shortened in search results. 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:type is missing. Twitter Card metadata is configured. The page declares 1 language or regional alternatives using hreflang.
