About this site
This site is intended to help diagnose client behavior. There are two versions of it:
- https://check-tls.akamaized.net/ - this version supports legacy clients including those not sending TLS SNI, but may not have the latest protocols enabled.
- https://check-tls.akamai.io/ - this version supports modern clients, but only those supporting newer ciphers and those sending TLS SNI
Other ways to test various types of clients:
- TLS SNI test image (returns if TLS SNI is present)
- IP version test image (returns if IPv4 or IPv6 is used)
- TLS version test image (returns if TLS 1.2 or earlier is used)
- TLS SNI test results in JSON format
- TLS SNI test results as an RSS feed
