Multi-Region SSL Checker
Validate SSL certificates from multiple global locations. Perfect for CDN and multi-region deployments.
About SSL Certificate Checker
Comprehensive SSL/TLS certificate analyzer that validates certificate chains, checks expiration dates, and verifies hostname matching from multiple global locations.
Key Features
Multi-region SSL validation
Certificate chain verification
Expiration monitoring
TLS version detection
Hostname validation
CDNs and globally distributed infrastructure can serve different SSL certificates from different edge locations. A certificate might be valid in US data centers but expired or misconfigured at European edges. Single-location SSL checks miss these critical inconsistencies.
Our multi-region checker validates SSL certificates from 6+ global locations simultaneously, catching regional deployment issues before they affect users. Essential for CDN configurations, multi-cloud deployments, and any infrastructure serving global audiences.
**Methodology:** Parallel TLS handshakes from 6 global regions comparing certificate fingerprints, expiry, and chain consistency.
Common SSL Errors & How to Fix Them
4 relevant issuesSSL works from some locations but fails from others. Common with CDNs and multi-origin setups.
Check all CDN edge locations have the same certificate deployed. Verify origin server certificate matches CDN. Purge CDN cache after certificate updates. Check if geo-routing serves different origins.
Browser shows "Your connection is not private" or NET::ERR_CERT_DATE_INVALID.
Renew your certificate immediately through your CA (Let's Encrypt, DigiCert, etc.). After renewal, deploy the new certificate to all servers and CDN edges. Clear CDN cache if using Cloudflare or similar.
Works in some browsers but fails in others. Mobile devices often affected first.
Include the intermediate certificate bundle when configuring SSL. Download the full chain from your CA and concatenate: your cert + intermediate(s). Test with openssl s_client -connect domain:443 -servername domain.
Certificate is valid but issued for a different domain. Shows NET::ERR_CERT_COMMON_NAME_INVALID.
Ensure your certificate includes all domains (www and non-www). Use a SAN certificate or wildcard (*.domain.com). Reissue if domains were missed during certificate request.
Frequently Asked Questions
4 relevant questionsCDNs and load balancers often serve different SSL certificates at different edge locations. A certificate might be properly deployed in US data centers but expired or misconfigured in European nodes. Regional mismatches can also occur during certificate renewals if not all edges are updated simultaneously. Multi-region testing catches these inconsistencies before they affect users.
CDNs typically terminate SSL at their edge and may use their own certificates (like Cloudflare's Universal SSL) or your uploaded certificate. If certificates don't match, check: 1) CDN SSL settings for custom certificate upload, 2) Origin pull settings if using Full (Strict) mode, 3) Whether CDN cache needs purging after certificate updates. Multi-region checks help identify edge-specific certificate issues.
Unlike DNS, SSL certificates take effect immediately on your origin server. However, CDN edges may cache the old certificate. Cloudflare: purge cache or wait 24 hours. AWS CloudFront: 15-60 minutes for distribution. Fastly: near-instant with purge. Always use multi-region testing after certificate updates to verify all edges are serving the new certificate.
Our health score (0-100) weighs: certificate validity across all tested regions (60%), days until expiry (20% - higher scores for >60 days), TLS version (10% - TLS 1.3 scores highest), and cipher strength (10% - 256-bit encryption preferred). A score of 80+ indicates excellent certificate health. Below 50 requires immediate attention.
