The Case of the Recursive Resolvers - Slack Engineering
Rafael Elvira Staff Software Engineer, Infrastructure On September 30th 2021, Slack had an outage that impacted less than 1% of our online user base, and lasted for 24 hours.

Hijacking the top-level domain of a sovereign state - Labs Detectify
Imagine what could happen if the country-code top-level domain (ccTLD) of a sovereign state fell into the wrong hands. Here’s how I (@Almroot) bought the domain name used in the NS delegations for the ccTLD of the Democratic Republic of Congo (.cd) and temporarily took over 50% of all DNS traffic for the TLD that could have been exploited for MITM or other abuse.

Cloudflare and Apple made a new DNS protocol to protect your data from ISPs
Cloudflare is proposing a new DNS standard it developed with Apple that’s designed to help close a blindspot in my (and I’m sure many others’) internet privacy measures (via TechCrunch).

Cloudflare outage on July 17, 2020
Today a configuration error in our backbone network caused an outage for Internet properties and Cloudflare services that lasted 27 minutes. We saw traffic drop by about 50% across our network. Because of the architecture of our backbone this outage didn’t affect the entire Cloudflare network and was localized to certain geographies. The outage occurred because, while working on an unrelated issue
