Description
In October 2021, a large social media platform experienced a widespread outage of its network. In this presentation, we will show how the outage led to a significant traffic increase on Verisign's authoritative name servers. Furthermore, we will show how this incident is similar to other events and conditions, and discuss our proposal for stricter protocol requirements on negative caching of DNS resolution failures.
