I know they lay down their own network cables.
I know they lay down their own network cables.
I cant readily find a link, but their rack-mount servers are I believe "custom" designs just for them (presumably done in-house too), although from what I know they use off-the-shelf CPUs from Intel and AMD (there was an announcement very recently that they were using Epyc now for example) & GPUs etc.
It would not surprise me if only the x86 CPUs & GPUs were the only external things they use, and I bet they're looking at their own custom ARM chips for certain workloads (like they use their custom TPUs for certain workloads).

But they probably use standard chipsets.
