ieslarra-informatica.blogspot.com Website Overview & Technology Report
We performed a comprehensive analysis of ieslarra-informatica.blogspot.com on 2026-06-30. The website returned an HTTP 200 status code with a server response time of 1754ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 133 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Google Trust Services (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 139 domain(s) (Subject Alternative Names) and expires on 2026-08-31, which is 62 days from now. The security headers analysis reveals a score of 15/100 (poor). The following security headers are properly configured: X-Content-Type-Options. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-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 4 technologies across 4 categories powering ieslarra-informatica.blogspot.com. The detected stack includes Angular, Google AdSense, Google Fonts, and YouTube Embed. The site uses Angular as its primary framework. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, ieslarra-informatica.blogspot.com receives an overall trust score of 60/100, classified as "Likely Safe".

ieslarra-informatica.blogspot.com Trust Score & Safety Analysis
After conducting a thorough safety and legitimacy analysis, ieslarra-informatica.blogspot.com receives a trust score of 60/100, 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 and a valid SSL certificate issued by Google Trust Services with 62 days until expiration. 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 ieslarra-informatica.blogspot.com 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.

Response time, compression, CDN usage, Core Web Vitals, and environmental impact metrics for ieslarra-informatica.blogspot.com.
ieslarra-informatica.blogspot.com Performance & Web Vitals Report
ieslarra-informatica.blogspot.com delivers its homepage in 1754ms (server response time), which is considered somewhat slow by industry standards. The total page weight is 133 KB, and we detected 146 resource requests loading assets from 27 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 4 CSS files and 0 out of 7 JavaScript files are minified. Minifying the remaining 11 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 ieslarra-informatica.blogspot.com produces approximately 0.06g 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 133 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for ieslarra-informatica.blogspot.com. 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.
