Maybe i read too much in to “depend on used hardware sales.” Ive worked for 2/5 and 3/15 largest us companies doing cloud and infra stuff. Recovered costs from EOL hardware has just never ever mattered. Not even a rounding error o

Bad news, 60/40 isnt a diversification strategy the last few years. 1) positive correlation in equity and fixed income 2) US treasuries/dollars have not had a “flight to safety” bump when volatility/l or bad news happens rece

They tried to do a LOT. An absolutely huge amount of work trying to abstract all of the existing Code* services, big chunks of other AWS services, and then corp (and non corp!) identity. The last part, getting human identity in to AWS, is s

I don't know if this comment is one of ignorance, or juvenile "well actually", but it is tragically misinformed. From an Australian perspective all of the big players, CSR, John Mansviille, & James Hardy, knew asbestos

Man I always hated that phrasing; always tried to get people to use more precise terms like “customer change propagation.” But yeah, who hasnt been punished by a queryplan change or some random connectivity problem in south east asia!

Akamai talked about it in the early 2000s. Facebook content folks had a decent paper describing the latency collection and realtime routing around 2011ish, something like “pinpoint” I want to say. Though as you say was industry practice bef

Some details, but yeah that's basically how all AWS DNS works. I think youre missing how labels, zones, and domains are related but distinct. And that R53 operates in resource record SETS. And there are affordances in the set relations

See https://news.ycombinator.com/item?id=45681136 . The actual DNS mutation API does, effectively, CAS. They had multiple unsynchronized writers who raced without logical constraints or ordering to teh changes. Without think

This is public messaging to explain the problem at large. This isnt really a post incident analysis. Before the active incident is “resolved” theres an evaluation of probable/plausible reoccurrence. Usually we/they would have pote

Terrible article. Im ex-AWS, left as a principal after 10 years to go take another global megacorps shilling. I dont even disagree with the premise, but its so clearly a predetermined conclusion written as opinion piece to fit the hot news

FYI: 1. AWS IAM mutations all go through us-east-1 before being replicated to other public/commercial regions. Read/List operations should use local regional stacks. I expect you'll see a concept of "home region" g

Not quite. Hardware with customer data or corp IP (eg any sort of storage or nvram) doesnt leave the "red zone"[1] without being destroyed. And reusing EOL hardware is a nightmare of failure rates and consistency issues. Its usual
