CloudFront 宣佈十年了，另外這次在東京又加節點了，變成 10 個：「Celebrating the 10 year anniversary of Amazon CloudFront by launching six new Edge locations」。
另外宣佈支援 WebSocket：「Amazon CloudFront announces support for the WebSocket protocol」，以及支援 Origin Failover：「Amazon CloudFront announces support for Origin Failover」。
WebSocket 算是大家等蠻久的功能，大家主要是希望利用 CloudFront 擋 DDoS，正常流量才往後丟。而 Origin Failover 則是可以設定兩個 Origin，當主要的掛掉時可以切到備用的，對於支援多節點的架構算是第一步 (目前看起來只能設兩個)：
With CloudFront’s Origin Failover capability, you can setup two origins for your distributions - primary and secondary, such that your content is served from your secondary origin if CloudFront detects that your primary origin is unavailable.
都是隔壁棚 Cloudflare 支援許久的功能... 算是補產品線與進度？
