I thought DARPA designed the internet to survive nuclear war - no single point of failure - clearly Facebook's network breaks that rule. They need a DNS of last resort that doesn't update fast.

- Telluur 5y agoOn your single point of failure. That might be true, but certainly isn't these days. Networks have grown so large and complex that the only reasonable way of managing them is through SDN, and a small mistake in configuration might results in a cascading effect on the whole infrastructure. That's also true for the entire (western) internet. We've ended up with a centralized market where a few key players, e.g. cloud providers/CDNs/DNS (Amazon/Google/Microsoft/Akamai/Fastly/Cloudflare) can easily break large parts of the internet. See Akamai outage in July.
