Its a cousin of the mindset that the reason people don't steal is because they think they will be caught and rationally weigh up based on the value they gain and the chance of loss that its not a worthwhile action.
No, most of the time people steal because they think its wrong, and they dont want to do it.
Public trust is a real thing and varies massively by country. America is notably extremly low on this metric
Do you want performance, or correctness.
Well, if you want performance you use write through caching and in the case of distributed storage: more nodes confirming the block before returning. Huge performance cost.
Outsourcing this just means someone else makes these tradeoffs, they will prioritise the general case- and they’re even more incentivised to move the needle towards things that are most visible to the end user.
In this case, performance.
You won’t notice that theres a third commit server off-site (unless that site is bombed), but you will notice slower writes- and the general case says that people will express comparative dissatisfaction with weaker performance and use it as a justification to use another provider.
So any software company/project which actually took the time and effort to fully handle the enormous complexity, they can't sell themselves based on that fact because every other company (who didn't invest the effort) is also claiming it and the customer has no mechanism to verify the claims until some major rare event occurs.
And most of the effort is required precisely to handle those 1% of rare situations.
So then that big thing comes to you. It’s all kind of … held together by a prayer …
Trust me I’ve worked at these big places. You wouldn’t believe how much fucking luck and grace from God is allowing you to do anything with your digital life. It’s a mindfuck of a tangled mess out there, eternities worth of written code that only God ensures works together at this point, only to get more hidden with AI.
For example, you mention Backblaze. Backblaze has public posts about their durability model. They claim to use 17:20 Reed-Solomon erasure encoding. That means there are 20 shards of a blob, and you can lose 3 of them and still reconstruct the blob.
Think about that for a second. If they store 4 shards in a datacenter, that means that a loss of that one datacenter is sufficient to lose the blob, forever. That entails that blobs are sharded across a minimum of 7 data centers, or the loss of one data center might mean permanent data loss. Which one do you think is true? (In fact it's pretty clear from Backblaze's public posts that they don't shard across data centers at all, only across racks within a data center.)
Now, AWS's availability guarantee — not their durability guarantee — entails that they use a less cost-effective erasure coding ratio. S3 is designed so that your blob is available even if a whole AZ goes down, and it's well known that most AWS regions have only 3 AZs. Therefore, if you tolerate the same number of shards lost to HDD failure as Backblaze in your durability model (3), then you might need 17:30 erasure coding to get the same durability and the required availability. That means S3 is storing way more physical bytes than Backblaze — 1.76x the logical size of the blob, instead of Backblaze's 1.18x. That's more expensive, but it also gives you better availability.
Which is also why One Zone S3 is cheaper — if you don't care about the availability guarantee, S3 can do what Backblaze does and save 33% on physical bytes, and they pass on 40–50% of those savings to the customer (this is fairer than it sounds — there's more overhead than physical storage bytes).
But here's the thing. AWS has more redundancy built in than Backblaze because they make availability guarantees in addition to durability guarantees. BUT the durability model is the same, which is why Backblaze can claim equivalent durability to S3. S3 in fact has better durability — they can survive the permanent loss of an AZ without necessarily losing blobs stored there (with the exception of One Zone blobs), and Backblaze cannot. But that's not actually a factor of the durability model, which is just taking into account normal events like HDD failure. Instead, S3 has durability that's more resilient to AZ loss because of their availability model. It's a side effect that isn't actually part of the durability promise!
Not disimilar to how AI naratives are pushed on executives these last two years.
If businesses are going to cloud but without engaging / listening to competent people who know these basics -- then the blame needs to be somewhat pointed back at those very business leaders I feel.
This is not obscure magical knowledge either that is tightly controlled. Any cloud vendor will freely teach you that. Or even a google search would.
I mean, every time cloud comes up on HN we see legions of techies posting strowman arguments about why you should offload everything onto AWS, GCP, Azure, etc.
https://docs.aws.amazon.com/fis/latest/userguide/what-is.htm...
But the problem is right there: "non-technical" leaders. Never work for one if you can avoid it.
I feel like if this was done correctly it would eat a bunch of the market, but I question how many people are actually willing to pay for "the right way". The last time I had that experience it was with Heroku which was quite a leaky abstraction.
And for that, with a simplified use case, well, they can scale up to $20k+ a month if they like, that would be ideal, and if they need a more complicated setup or enterpriseyness, migrate off with my blessing and available-not-required hands on support (again for a reasonable fee, maybe $10k if you want the white glove).
This is true. The latter half of your comment is not. At best they have a duty to shareholders. But your assertion would mean every time a company posted a loss and the price went down the execs would be in legal trouble, which is nonsense.
Something bad happens, stock goes down, angry shareholders sue because they should have been told the bad thing would happen and the stock would go down.

Cue security entitlements, e.g. https://ndlegis.gov/assembly/69-2025/testimony/SJUD-2364-202...
There are plenty of companies who pay no dividends and have not returned growth in share price. They’re still operating and no one’s coming to throw the execs in jail.
On the off chance that there is such a law, please cite it.

> This dysfunction manifests itself primarily through the reduction of democracy to a legalistic logic, as neoliberalism has imposed a conception in which the law—elevated to the status of exclusive guarantor of individual liberty—relegates the political realm to a purely managerial function.
Of course that all this is kind of circular, meaning the (neo-liberal) morality imposing itself via law on the current (and by now surpassed) morality, but that's how things usually go when it comes to societal theory.
It's very clearly not about you being able to set-up redundancy for yourself.
But it's not designed to survive TWO datacenters going offline, and in a permanent fashion.
_You_ are supposed to have three copies of everything - and two of those should be off AWS.
But when I put data on normal S3, isn't my money supposedly paying for triple redundancy?
Look, here's the documentation: https://docs.aws.amazon.com/AmazonS3/latest/userguide/DataDu...
"S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, and S3 Glacier Deep Archive redundantly store objects on multiple devices across a minimum of three Availability Zones in an AWS Region. An Availability Zone is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region."
As far as I've heard before that's not with parity and three zones means three copies. But when I search now I see things about 5+4 parity, any insight here?
Not just in terms of service costs, but in time and complexity. In many cases building out that complexity is complicated and difficult. And sometimes the functionality you need isn't supported in the regions you use.
Amazon only claims "99.999999999% durability" per year, even for the properly replicated stuff.[0]

Now I'm thinking about legal/contractual rules that might force that kind of geographic risk.
I mean, logically you could have the Allowable Location send pre-encrypted backups to anywhere in the world, except (A) laws and regulations aren't always logical and (B) you still have the problem of keeping the decryption keys somewhere safe without leaving the key jurisdiction.
Bezos has been working with Trump. The instability has been hugely exacerbated by Trump. The issue lies at home.
They could, of course, open other regional data centers in other countries, or say "data in this geo zone may be in any of X, Y or Z" countries, but for the latter that pretty starkly limits some of the major customers they'd have, I would guess, and for the former, well, they have other geo zones already, so if people weren't replicating to them, I'm not sure why adding me-east-1 me-west-1 me-central-1 would fix that issue, they just wouldn't replicate there either.

There's a lot of magic & handwaving from hyperscalers like AWS about redundancy. I always wondered about some of the engineering to make this absolutely (and literally) bullet proof. At the end of the day most of their answers when you push hard enough involved paying 2-3x to run everything across multiple zones/regions, and lots of awareness in your application to handle this.
In any case, I think it's good that when a data center blows up the data is lost. Noteworthy for future skynet situation, etc.
Doesn’t really apply, because the only reason data was lost is because customers chose not to replicate it to other regions, either because of legal data residency requirements, cost, or just not bothering.
If Skynet wants to make sure it’s backed up, none of that prevents it from doing so. Although it would be amusing if Skynet was stopped by a billing alert when it tries to copy itself to another region.
A perfect example of a claim they never made.
He is also violating an enormous amount of compliance requirements, by disclosing the location of the data center, and having strange people inside making a tour. Did he vet the crew and their accompanying party? Did one of them accidentally left some kind of device within the insider perimeter? There at least one or two ISO certifications he is violating there. As customer I would be asking questions...
AWS always made very clear they wont copy your data to another region as only you know what your compliance and data residency requirements are. But at the same time they always said, its up to you to come your with your disaster recovery strategy based on your project requirements. And it has always been the case copying your critical data to another region is one of the first things on your check list.
And their Well Architected Framework and other docs make this plenty clear:
"It is a good practice to always make backups of your data, and copy these to another site (such as another AWS Region)."
Also...
"All DR strategies require that data sources are backed up within the AWS Region, and then those backups are copied to the recovery Region."
And also for single-Region / Multi-AZ architectures:
"Where possible, you should also copy data backups to another AWS Region as an additional layer of protection."
"AWS Architecture Blog — Disaster Recovery Architecture on AWS, Part II" has a whole section named "Backup to another AWS Region": "By copying your data to another Region, you can handle the largest scope of disasters."
https://aws.amazon.com/blogs/architecture/disaster-recovery-...
Or "Creating backup copies across AWS Regions" - https://docs.aws.amazon.com/aws-backup/latest/devguide/cross...
This whole thread of people literally saying , "on no I trusted them...I did not know they could lose my data", with no technical context...is the the kind of incompetence I would expect from a generation raised on vibe coding and llm prompt driven miseducation...
Obviously here, he should have mentionned that they can recover a hit on a single data center, provided the customer chose multi-AZ hosting. That's probably why companies run their ads on "This watch is a legacy for your children" rather than any material claim.
Now, there are a few things to consider:
- AWS best practices recommend multiple AZs for workloads and cross-region backups for things like databases and other “stateful” data
- You have to read the fine-print on what AWS offers in terms of recovery: do they reffer to their own infrastructure when they say “you won”t notice” or your data
When Google’s Paris colocation facility was flooded and all AZs there went dark, they sent an email saying “restore from backup in another region and if we can restore your data, we will make it availbale to you”. They did not even issue credits for the downtime.
An extraordinary statement itself that shows the difference between a proper cloud where they AZs are at least 60 to 100 miles apart...and Google or Microsoft... pretend clouds...where those AZs are just firewalls across the same data center...
this is one of one of those things - were in the current era either a cloud provider should provide automatic backups in another geographic zone.
if you're in us-east, then your back-ups should ideally be in eu-west + africa for redundancy.
The amount of data S3 stores "automatically replicating" to other geographical locations would make things prohibitively expensive, especially when you consider the daily delta, and how much of that is ephemeral or frequently mutated data that is stored. The bandwidth costs alone would be eye-watering, let alone the storage costs.
S3 cannot make any automated decision about whether data is, or isn't important, and if they did they'd only open themselves up to lawsuits if they guessed wrong. That's why it's made an option for the end user to enable replication if they want to, or choose to replicate their own data.
It did work like this! And it was! My recollection is that the first S3 was out of SEA and had no user concept of region. Then “VDC” was added in virginia. That provided API endpoints in what became us-east-1. A bucket could be accessed from either location, and the original intent was for object store to replicate between them. By the time dub/eu-west-1 came along that was obviously not tenable; itd take 10s of gbs to replicate.
So S3 became regional. But the original sea/vdc deployments still had shared APIs and data in both regions. Your object would be stored in the region of the API you geolocated to via DNS, but read from either. _eventually_ all the data migrated to IAD, but those API endpoints were transparently proxying across the continent until 2013 or so.
And of course glacier had much more interesting takes on this with cross dc/az/region erasure encoding. But i dont think any of the wacky multi dimensional cross region stuff ever materialised in practice.
PS: hi!
2013-2014 would be about right, they were still in SEA when I joined in 2013 but were actively working on decommissioning it.
