If Musk says it's DDOS then it's almost certainly not DDOS.

I wouldn't have believed this a few years ago but I do now. If you sell your soul to the biggest liar on Earth, then you are complicit and probably have similar neurological patterns.

I wouldn't call it tracing, but the usual mitigation is block IPs.

Depending on the nature of the DDoS, you may block it at other parts of the stack.
