It's possible that I've simply not hit the corresponding circuit breakers but no issues with AWS for similar launches and spikes in traffic. It's expensive though, and my experiment with Hetzner was a misguided effort to reduce costs.
I confronted Netcraft about it and they just told me that they didn't actually detect anything like criminal activity, but they need to say that or else Amazon won't take their reports seriously. Pretty fucked IMO.
yeah, because their business model is to hope you have very expensive spikes. legitimate or not
