If an amount of traffic that nobody else even notices brings you to your knees, you're doing something wrong. Go could be far more efficient but pointing at this and calling it a DDoS is silly.
You are correct, it was more a complaint about resource usage and costs, as opposed to a breakage of the src.ht service.
I called it a DoS, not a DDoS.
Technically it'd be a DDoS, but however distributed it is makes no difference to what we're talking about here. If you could respond to substance, it'd be appreciated.
