I had a customer that was getting DDoSed by competitors, the competitors likely didn't know they were doing a DDoS, as they were aggressively scraping product listings but just doing so without any delay/rate limiting and it effectively DDoSed them. They weren't trying to make the target site slower, but were trying to get data at a rate that made the target's servers uneconomical to their actual paying customers. This kind of attack is nothing like the actual DDoS attacks, but it's a lot more common in my experience, but also relatively easy to mitigate with something like Cloudflare or Akamai (which is what I'd recommend to my customers).
