I ran a website with 37 million users and 3.6Gbps peak bandwidth (JavaScript+thumbnails, no video) from my own two racks of Linux servers thay i have not systematically updated for years. The OSes were beyond the lts support winows. I manually compiled my own updates, but very rarely and only those that i deemed critical. Granted, the site stack was completely custom so the standard automated hacks didn't work. In 15 years there were no accidents.
