Google and FB (and apple, but less so?) -- have been making their own servers and hardware for years... They protect this aggressively, and the tech is impressive. I remember the first time I accidentally saw a custom google node when I went there to pick a friend up from there, and I had gone to his desk and I saw a really nice looking PCB on his desk he forgot about, and I exclaimed "WHATs that' -- I was pretty familiar with a wide range of server boards, and I knew that was custom immediately... He panicked covered it and we didnt really talk about it much, but it was known really early that they were building a lot of custom kit. ~2005 maybe?
