Speaking as a former Blog Bar Raiser, cperciva has internalized the AWS blog style guide better than most Amazonians. This is spot-on.
(In all seriousness, I've been reading AWS launch posts for 20 years; this one was mainly imitating the S3 Files launch post but I diverged by adding the customer quote and the FAQ -- because of course I started this process with a PRFAQ, and some of the questions in the FAQ are legitimately important.)
As a non-Amazonian I've never seen it, of course.
PS: you might get tripped up on 0x00, 0x2F, or similar control characters? As i recall any valid octet can be included in a label. We definitely saw literal ‘*’ and ‘.’ inside labels. And I wouldnt be surprised to find a bell in there either.
A little bit of Canadian/non-American English slipped in (eg. enrol, behaviour), which AFAIK would have been flagged for a real Amazon post because as Americans we were brave enough to get rid of the 'U' in a lot of British words, like 'colour' and 'armour'.
But by God, we kept the British 'U' in the word 'glamour'.
As a heavily disaffected American (who still can't wrap his head around the fact that we let this happen twice) I support any form of protest against us.
