Cloudflare endured some attacks in the near past that came from devices that had port 23 (telnet) open or closed, never filtered. Most of the hosts were Vietnamese networks that looked like connected CCTV cameras. Multiple had open port 80 with presenting “NETSurveillance WEB” page. These were all hints that the attacks were coming from an IoT (Internet-of-Things) category of devices. Cloudflare team measured these attacks by the number of requests and bandwidth.

Facebook’s internal CDN for live videos

Live for Facebook Mentions is a feature that enables Facebook users to stream live video, and for this, they’ve rolled out their internal CDN (Content Delivery Network). This move brought with it a host of vexing logistical issues which needed to be solved. Problems like traffic spikes (thundering herd problem) and load balancing needed to be addressed for millions of users trying to access different live streams. Now, rather than letting clients connect directly to the live stream server, Facebook set up a globally distributed network of global edge caches. They’ve also enabled RTMP playback to shorten the latency in live broadcasts to just a few seconds.
