yen-joy.net

We performed a comprehensive analysis of yen-joy.net on 2026-06-30. The website returned an HTTP 200 status code with a server response time of 22590ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 3150 KB, and the site is served behind a CDN (Content Delivery Network). The website uses a secure HTTPS connection with a valid SSL certificate issued by Amazon (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_128_GCM_SHA256 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 2 domain(s) (Subject Alternative Names) and expires on 2026-12-03, which is 156 days from now. The security headers analysis reveals a score of 65/100 (moderate). The following security headers are properly configured: Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. However, the site is missing Strict-Transport-Security (HSTS) and Permissions-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 6 technologies across 6 categories powering yen-joy.net. The detected stack includes Angular 21.2.17, Vite, Google Analytics 4, reCAPTCHA v3, Amazon CloudFront, and Google Fonts. The site uses Angular as its primary framework (version 21.2.17). Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, yen-joy.net receives an overall trust score of 76/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, yen-joy.net receives a trust score of 76/100, 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, a valid SSL certificate issued by Amazon with 156 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, and DMARC email authentication with a quarantine policy. 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 yen-joy.net 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.

yen-joy.net delivers its homepage in 22590ms (server response time), which is considered slow by industry standards. The total page weight is 3150 KB, and we detected 669 resource requests loading assets from 9 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 3 CSS files and 0 out of 5 JavaScript files are minified. Minifying the remaining 8 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 yen-joy.net produces approximately 1.54g of CO₂, earning a carbon rating of F. The website's carbon footprint could be reduced by optimizing images, enabling compression, reducing third-party scripts, and leveraging caching. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 3150 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for yen-joy.net. 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.

yen-joy.net resolves to the IPv4 address 18.165.122.31 and also supports IPv6 (2600:9000:2375:7400:1c:f2e:fe40:93a1), demonstrating modern network infrastructure readiness. The domain has 4 A record(s) configured. The domain name system is managed by 4 name servers: ns-1372.awsdns-43.org, ns-1935.awsdns-49.co.uk, ns-572.awsdns-07.net, and ns-68.awsdns-08.com. Having 4 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 yen-joy.net is handled by amazonaws.com with 1 MX records configured: inbound-smtp.us-east-1.amazonaws.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 (Domain-based Message Authentication, Reporting and Conformance) is configured with a quarantine policy — a moderate setting, directing unauthorized emails to spam/junk folders. 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 yen-joy.net. 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.
