I’m familiar with Google’s custom SKUs, and I assure you they’re unique enough to experience microcode bugs nobody else on the planet ever hits. There was a weird FDIV one back in the day that wasn’t the same FDIV bug that hit us all a long time ago. Cloudflare isn’t really at that customization table. Your take sounds accurate for non-FAANGs (and a couple of those). For Google, not so much. There is a lot of custom acceleration and such that isn’t available to any other customer, and a nearby commenter is right, every detail about them is locked behind a very strong NDA. I’ve heard thirdhand AWS does indeed have custom instructions in the virtualization extensions stuff, but don’t know if that’s true.
