I’ve recently updated this blog and icanhazip.com to enable HTTP/2! This probably won’t have much of an effect on users who query icanhazip.com with automated tools, but it should deliver the content on this blog a little faster. If you’re using an older, non-HTTP/2 client — don’t worry. All of the sites will continue working for you as they always have.
Head on over to Wikipedia to learn more about HTTP/2 and its benefits.
Also, I’ve revised the list of allowed TLS ciphers so that stronger ciphers are required. If you’re having issues with a particular client, please let me know.
