What's your barometer for "bizzare" though?

The sad reality is that anyone running a website on the Internet these days is target for a DDoS, you only have to piss off the wrong somebody with 5 cents of sense and $50 of Bitcoin. Your personal website about birds you saw could get DDoSed by your neighbor who thinks you're lying about seeing more birds than him. To be clear, most sites will be unmolested and if it's a small personal site, just taking it down until the attacker gets bored is certainly one option. But if it's something business related you don't really have that option.
