16-17saver.co.uk Trust Score & Safety Analysis
After conducting a thorough safety and legitimacy analysis, 16-17saver.co.uk receives a trust score of 70/100, 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, and SPF (Sender Policy Framework) email authentication preventing email spoofing. Areas of concern include: the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked 16-17saver.co.uk against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal.

Response time, compression, CDN usage, Core Web Vitals, and environmental impact metrics for 16-17saver.co.uk.
16-17saver.co.uk Performance & Web Vitals Report
16-17saver.co.uk delivers its homepage in 13261ms (server response time), which is considered slow by industry standards. The total page weight is 25 KB, and we detected 95 resource requests loading assets from 20 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: 2 out of 8 CSS files and 8 out of 11 JavaScript files are minified. Minifying the remaining 9 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. The site is served through a Content Delivery Network (CDN), which caches static assets at edge servers around the world. This means visitors from different geographic regions receive content from the nearest edge server, significantly reducing latency. CDN usage is particularly important for websites with a global audience, as it can reduce page load times by 40-60% for distant visitors. From an environmental perspective, each page view of 16-17saver.co.uk produces approximately 0.01g of CO₂, earning a carbon rating of A. 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 25 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for 16-17saver.co.uk. 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.

16-17saver.co.uk DNS Records, Email Authentication & Domain Registration
16-17saver.co.uk resolves to the IPv4 address 13.33.235.38 and also supports IPv6 (2600:9000:20a8:b200:d:cd0d:c400:93a1), demonstrating modern network infrastructure readiness. The domain has 4 A record(s) configured. The domain name system is managed by 2 name servers: erin.ns.cloudflare.com and jason.ns.cloudflare.com. Having 2 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 16-17saver.co.uk is handled by emailarray.com with 2 MX records configured: mx.emailarray.com and mx2.emailarray.com. 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 is not configured, leaving the domain vulnerable to email spoofing and phishing attacks that impersonate this domain. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is not enabled for 16-17saver.co.uk. While not critical for most websites, DNSSEC adds an important security layer by ensuring DNS responses haven't been tampered with during transit. Enabling DNSSEC is recommended for domains handling sensitive data or financial transactions. Our subdomain enumeration scan discovered 2 active subdomains for 16-17saver.co.uk: webmail.16-17saver.co.uk and www.16-17saver.co.uk. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.
