- pay a shady botnet to do it for you

- buy a bunch of VMs and curl your site's weakest point (don't wait for the http response) / use loadtesting tools

- change the site infra to support 1 request per second at most, and hit it with 2! :D

- posting the url here will get you far

- develop an app for your site, make it super popular and let it call home (an unidentifiable and cache breaking request -- many have fallen to this)

Depending on the deployment and the site's infra, this can be trivial. Or you might need to pay a botnet (or create an app with x milion downloads, whatever is easiest).
