e-uchina.net

We performed a comprehensive analysis of e-uchina.net on 2026-07-01. The website returned an HTTP 200 status code with a server response time of 10248ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 448 KB. 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 2027-02-17, which is 231 days from now. The security headers analysis reveals a score of 0/100 (poor). No security headers are configured, which is a significant security concern. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, 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 10 technologies across 9 categories powering e-uchina.net. The detected stack includes WordPress, WooCommerce, Vue.js, Google Analytics 4, Hotjar 672720, Google Tag Manager, reCAPTCHA v3, GitHub Pages, jQuery, and Font Awesome. The primary e-commerce platform is WooCommerce. The UI is built with Vue.js. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, e-uchina.net receives an overall trust score of 66/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, e-uchina.net receives a trust score of 66/100, 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 231 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 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, 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 e-uchina.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.

e-uchina.net delivers its homepage in 10248ms (server response time), which is considered slow by industry standards. The total page weight is 448 KB, and we detected 611 resource requests loading assets from 30 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: 4 out of 8 CSS files and 8 out of 14 JavaScript files are minified. Minifying the remaining 10 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 e-uchina.net produces approximately 0.22g 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 448 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for e-uchina.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.

e-uchina.net resolves to the IPv4 address 76.223.50.144, but does not support IPv6. IPv6 adoption is increasingly important as IPv4 address space becomes exhausted, and some ISPs and regions are transitioning to IPv6-only connectivity. The domain has 2 A record(s) configured. The domain name system is managed by 4 name servers: ns-1208.awsdns-23.org, ns-2032.awsdns-62.co.uk, ns-339.awsdns-42.com, and ns-592.awsdns-10.net. 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 e-uchina.net is handled by amazonaws.com with 1 MX records configured: inbound-smtp.us-west-2.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 e-uchina.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.

The homepage of e-uchina.net contains 623 words of visible text content. This is a moderate amount of content. The page is structured with 31 H2 headings, 34 H3 headings, 1 H4 headings, 0 H5, and 9 H6 headings. The page includes 136 images. 62 images (46%) are missing alt text attributes, which is a significant concern for both accessibility and SEO. Screen readers rely on alt text to describe images to visually impaired users, and search engines use alt text to understand image content. Only 54% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 318 internal links pointing to other pages on the same domain and 31 external links pointing to third-party websites. The high number of internal links suggests a well-interconnected site structure, which helps search engines discover and crawl all pages efficiently. There are 14 external JavaScript files, 8 CSS stylesheets, and 1 iframes on the page. The site implements the following web standards and features: robots.txt (controls search engine crawling behavior), Schema.org structured data (BreadcrumbList, ImageObject, ListItem, Organization, WebPage, and WebSite), Progressive Web App (PWA) manifest (enabling app-like installation), and RSS feed for content syndication. Notable missing features: XML Sitemap. Adding these could improve search engine discoverability and rich result eligibility. The website has social media presence across 1 platforms: Instagram (@uchina.life.okinawa). An active social media presence is a positive trust indicator and helps build brand awareness and customer engagement.
