bortzmeyer.org

We performed a comprehensive analysis of bortzmeyer.org on 2026-07-08. The website returned an HTTP 200 status code with a server response time of 7883ms. The page is served over HTTP/1.1 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 341 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Let's Encrypt (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_256_GCM_SHA384 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 1 domain(s) (Subject Alternative Names) and expires on 2026-09-23, which is 77 days from now. The security headers analysis reveals a score of 35/100 (below average). The following security headers are properly configured: Strict-Transport-Security (HSTS) and Permissions-Policy. However, the site is missing Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy, which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 5 technologies across 4 categories powering bortzmeyer.org. The detected stack includes Drupal, Vite, Cloudflare, Akamai, and GitHub Pages. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, bortzmeyer.org receives an overall trust score of 77/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, bortzmeyer.org receives a trust score of 77/100, which places it in the "Likely Safe" category. This score is calculated by evaluating multiple factors including SSL certificate validity, domain registration history, email authentication protocols, security header configuration, and blacklist status across major threat intelligence databases. The analysis identified several positive trust signals: a valid HTTPS connection protecting data in transit, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, a valid SSL certificate issued by Let's Encrypt with 77 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a none policy, and DNSSEC providing authenticated DNS responses. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), missing Referrer-Policy, potentially leaking URL information to third parties, and the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked bortzmeyer.org against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal. The domain passed all 8 checks with a clean status, meaning it has not been flagged for phishing, malware distribution, spam, or other malicious activities by any of the tested threat intelligence providers.

Our technology detection engine scanned bortzmeyer.org and identified 5 distinct technologies across 4 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. CMS: Drupal — manages the content and page structure for bortzmeyer.org. Build Tool: Vite — bundles and optimizes the JavaScript and CSS assets for bortzmeyer.org. CDN: Cloudflare and Akamai — accelerates content delivery by caching assets at edge locations worldwide for bortzmeyer.org. Hosting: GitHub Pages — provides the server infrastructure for bortzmeyer.org.

bortzmeyer.org delivers its homepage in 7883ms (server response time), which is considered slow by industry standards. The total page weight is 341 KB, and we detected 955 resource requests loading assets from 116 third-party domains. A high number of third-party domains can significantly impact page load time due to additional DNS lookups and TLS handshakes required for each domain. The website uses Gzip compression for text-based assets, achieving an estimated 60.0% reduction in transfer size. This reduces bandwidth usage and improves page load times, especially for visitors on slower connections. Asset minification status: 0 out of 2 CSS files and 0 out of 0 JavaScript files are minified. Minifying the remaining 2 unminified file(s) could further reduce page weight by 10-30% for those assets. Minification is a best practice that reduces download sizes without affecting functionality. From an environmental perspective, each page view of bortzmeyer.org produces approximately 0.17g of CO₂, earning a carbon rating of B. This places the website among the cleanest on the web, demonstrating efficient use of server resources and optimized content delivery. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 341 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for bortzmeyer.org. This typically means the site doesn't have enough real-world Chrome user traffic to generate statistically significant field data, or the domain is not included in the CrUX dataset. Core Web Vitals (LCP, INP, CLS) are important Google ranking factors that measure real user experience.

bortzmeyer.org resolves to the IPv4 address 92.243.4.211 and also supports IPv6 (2001:4b98:dc0:41:216:3eff:fe27:3d3f), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 7 name servers: ns-global.kjsl.com, ns.eu.org, ns1.bortzmeyer.org, ns1.shaftinc.fr, ns2.bortzmeyer.org, ns2.shaftinc.fr, and ns4.bortzmeyer.org. Having 7 name servers provides good redundancy — if one fails, the others can continue serving DNS queries. The choice of name servers often indicates the DNS hosting provider or CDN service being used. Email for bortzmeyer.org is handled by bortzmeyer.org with 1 MX records configured: mail.bortzmeyer.org. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF (Sender Policy Framework) is configured, which specifies which mail servers are authorized to send email on behalf of this domain. This helps prevent email spoofing and improves email deliverability. DMARC (Domain-based Message Authentication, Reporting and Conformance) is configured with a none policy — a monitoring-only setting that doesn't enforce any action on unauthorized emails. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is enabled for bortzmeyer.org, providing an additional layer of security by cryptographically signing DNS records. This prevents DNS cache poisoning and man-in-the-middle attacks that could redirect visitors to malicious websites.
