Anybody know who the "Cloudflare customer, a hosting provider" was and what IP they were targeting and why? I'm curious why someone would go to such great lengths to try to take down a service.
I don't know who the provider is, but the attack was almost certainly not targeting the provider, but a site hosted on their platform. Many hosting companies upsell their customers into stuff like providing Cloudflare DDoS prevention. The target site was probably something political or controversial. I work at a hosting provider and we deal with this type of thing constantly.
