Yes and no. Sure, Amazon has administrative personnel. Sure, some of those administrative personnel would probably be happy to get paid extra to carry a pager and be summoned to work at 3AM to update a status page.

But the last thing you want to do is put inaccurate information onto a status page; so mere administrative personnel isn't enough -- you'd need people who understand enough about the system to be able to write about it without introducing errors.

I'm guessing that the intersection of "administrative personnel", "willing to carry pagers" and "understand the internals of AWS services" is a very small set.
