Ive dealt with this error at AWS. It’s a unit error. In my case we _meant_ to charge like 5¢/GB, but missed the unit (GB), and then the billing system defaults to bytes. 5¢ per Byte of data transferred meant some customers were seeing MM bills within hours. Got paged by support around 2am, had it fixed and amendments issues by 3-4am, apology emails shortly after. Services emit metering values that arent directly tied…

#472Earlier quoted context omitted.
The user is asking me to calculate how much money they should charge their customer. The values they've given me are 0.45, 1.67, and 2.50. This is 2.50 + 1.67 + 0.45 = 4.62, but it could be any other number. Perhaps we should be concatenating the numbers instead. Wait! The . could also mean multiplication. 0 . 45 . 1. 67 . 2 . 50 = 3015000. But wouldn't multiplying by 0 zero it out? That can't be right, we wouldn't b…
Would be funny if it wasn't so close to true

#473AWS saw Anthropic billing a guy for $16 million on zero usage and thought, why stop at the millions? https://www.techtimes.com/articles/320266/20260712/anthropic...
That sounds bad.

No tests? Just mess up some mundane detail [1] and voila! Wake-up calls and heart attacks for 100,000s of administrators? 1: "Oh, well, this is not a mundane detail, Michael!" https://www.youtube.com/watch?v=3fGHaVn5rGo
Like maybe if the bill amounts increase by like 10M% there should be someone that looks into it

#476I once got a credit card statement that said estimated time to repay ....... more than 100,000 years. It was discouraging but I did pay it off. And sooner than estimated.

AWS is basically a utility. I think it's inevitable that their carelessness around billing will end up with them being regulated like one.
I can't think of another regulated utility that doesn't provide service to (essentially) all humans directly in their homes. Everyone knows what water and electricity are, the vast majority couldn't explain what service AWS provides.
AWS has plentiful competitors. If you don't like their behavior, don't patronize them!

#478From their status page >The second path involves rolling back a recent change to the billing computation subsystem. Want to bet AI code was involved?
How is 1 + 1 = 2 hard to test?
Vibe coded implementation paired with vibe coded tests made to fit the implementation?

Not even tests but just some basic anomaly detection lol. Like maybe if the bill amounts increase by like 10M% there should be someone that looks into it
You'd be better off letting the heart attacks happen and take the 3am on-call and be the hero instead. It would be good promo doc material, and being a hero is extremely good insurance against getting kicked out of the country (via the PIP->H1B grace period expiry mechanism).
