i'm sorry but this author has failed to point out the most commong cause for why a site goes down. it's not because of failing to cache...etc...most dbs will cache for you anyway... the main reason is because you probably are on apache and serving static assets directly w/o hosting them off a CDN or nginx/litespeed. if your page had 150 images/js/css combined, that's 150 hits hitting your server per page load. now multiply that by 100's or 1,000's+ visitors HN brings to your site at any given moment, ofcourse it will go down. apache isn't really good at serving static files, just relieving static assets off to cdn/fileserver is huge.
