cgca.uwm.edu

The domain cgca.uwm.edu, belonging to the University of Wisconsin-Milwaukee, presents an intriguing case study. With a trust score of 45, indicating "Caution Advised," this analysis aims to uncover the underlying factors that contribute to its reliability. Notably, the domain's response time is 921ms, which may be a concern for users with slower internet connections.

The trust score of 45 suggests that users should exercise caution when interacting with this domain. The low score is likely attributed to the absence of critical security measures, such as SPF and DMARC records. Furthermore, the domain's SSL certificate is issued by Let's Encrypt, a reputable authority, but the TLS version is 1.3, which may be a relatively new and potentially less widely adopted protocol.

The domain employs two technologies: Bootstrap and StackPath. Bootstrap, a popular front-end framework, is commonly used for web development. StackPath, on the other hand, is a content delivery network (CDN) that can improve website performance and security. The presence of these technologies suggests that the domain is well-equipped to handle modern web development challenges.

cgca.uwm.edu delivers its homepage in 921ms (server response time), which is considered average by industry standards. The total page weight is 20 KB, and we detected 72 resource requests loading assets from 16 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: 1 out of 2 CSS files and 0 out of 0 JavaScript files are minified. Minifying the remaining 1 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 cgca.uwm.edu 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 20 KB is the primary factor in this calculation.

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.

The domain is hosted at IP address 185.199.108.153, which may be a shared or dedicated server.

This lack of transparency may raise concerns about the domain's reliability and security.
