Do we even know how a server works? I am pretty sure blizzard constructs a server best as possible with the technology that is available to them. OTHER companies with LOWER quality standards than blizzard make the junk. Blizzard uses the best available because they are a gaming company not a server tech company.

We don't even know how it works. I don't know how it works. But I am guessing blizzard does NOT design every aspect of their servers from scratch 'in-company'. Pretty sure somethings related to the server are outsourced.
