Just because it was working doesn't mean there wasn't a ton of code stitching it together in the background that had to constantly be monitored for "issues". There's a lot more to a website than what you see on the pages that get served to your browser. One thing that only tends to get noticed when it breaks, and sometimes not even then unless someone actively attacks the site, is security. I won't pretend to know exactly what they might've been duct taping as I've never actually administered a site for myself (I did try at one point, but Apache's security settings confuse me), but suffice to say if you think it's "fine" just because pages get served in the form you expect and in a timely manner, you are making too many assumptions.
