kcbark.net now runs over HTTP/2!

What is HTTP/2 you ask?

From https://tools.keycdn.com/http2-test:

HTTP/2 is the first major HTTP protocol update since 1997 when HTTP/1.1 was first published by the IETF. The new HTTP protocol is needed to keep up with the exponential growth of the web. The successor of HTTP/1.1 brings significant improvement in efficiency, speed and security and is supported by most modern web browsers. A list of browsers that support HTTP/2 can be found on caniuse.com.

HTTP/2 is binary, instead of textual.
It is fully multiplexed, sending multiple requests in parallel over a single TCP connection.
It uses header compression HPACK to reduce overhead.
It allows servers to "push" responses pro-actively into client caches instead of waiting for a new request for each resource.
It uses the new ALPN extension which allows for faster-encrypted connections since the application protocol is determined during the initial connection.
It reduces additional round trip times (RTT), making your web-site load faster without any optimization.
Domain sharding and asset concatenation is no longer needed with HTTP/2.

HTTP/2 introduces other improvements, more details: HTTP/2 RFC7540
