"Many major websites and services were unreachable for a period Friday afternoon due to issues at Cloudflare’s 1.1.1.1 DNS service. The outage seems to have started at about 2:15 Pacific time and lasted for about 25 minutes before connections began to be restored. Google DNS may also have been affected... Despite much speculation as to the cause of the outage, there is no evidence that it was caused by a denial-of-service attack or any other form of malicious hackery... Discord, Feedly, Politico, Shopify and League of Legends were all affected, giving an idea of the breadth of the issue. Not only were websites down but also some status pages meant to provide warnings and track outages. In at least one case, even the status page for the status page was down...." https://techcrunch.com/2020/07/17/c...taking-a-large-piece-of-the-internet-with-it/
Cloudflare statement: "This afternoon we saw an outage across some parts of our network. It was not as a result of an attack. It appears a router on our global backbone announced bad routes and caused some portions of the network to not be available. We believe we have addressed the root cause and are monitoring systems for stability now." https://www.cloudflarestatus.com/
As Cloudflare have grown and become responsible for vast amounts of the internet, each time they go down it is a bigger problem. "Don't put your eggs in one basket" is as valid now as when your Grandmother said it. The internet was a semi-robust and self adapting system because it wasn't centralised. As big companies monopolise it more and more they themselves become the threat to the robustness of the net.
I run Quad9 DNS with AdGuard DNS as back up. Don't we all use two just in case a primary DNS server falters?
