AWS: Inaccurate Estimated Billing Data – $1.7 billion

URL already posted: https://health.aws.amazon.com/health/status

I've got an estimated bill for $1.7 BILLION over this month. Normal usage is < $5.

Obvs have created an urgent AWS support ticket. Anyone else seeing something like this?

Update: Reddit link: https://www.reddit.com/r/aws/comments/1uyuaw7/help_my_bill_s...

I 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.

That's good for the credit card company, they can project stable revenue 100k years into the future.

Probably the closest I've ever been to getting a heart attack. Normally <$1 per month, and now suddenly $284,006,266,443.74. Whatever the bug is on their end, this is unforgivable.

Yeah, this one is bad because it’s off by so much I’m shocked it wasn’t caught by tests, alerts about unusual changes in the billing system, or even accounting. Like surely the P&L reports look all kinds of wrong right now, they have to be showing like 6M% profit margins and revenue measured in quadrillions.

I’m also a little surprised this didn’t trip a circuit breaker. For something as non-real-time as billing, I’m surprised they don’t have an automated kill switch that pauses the billing system and fires a page if variance in bills spikes. Naively some kind of “if the standard deviation of customer bills for this year changes by more than 50%, pause the billing system”. At that number of customers, those numbers should be pretty stable beyond internal billing changes they could normalize for.

If I were to guess this bug is in the "display" part of the system which is probably distinct from the "actually take money from the customer" part of the system. One can imagine they have gates on the "actually take money" part, especially for a large bill like ours which was ~$300b or about 2.5x AWS' 2025 revenue... In one month. Surely if we had actually accumulated that bill they would be the ones with the problems when we can't pay it.

I don’t know how something like this makes it to prod. That’s multiple levels of failure.

Same here. I got an email with a bill of $233 million and an estimated $433 million until the end of the month. I panicked and nuked my entire setup (which wasn't used that much, anyway, the alert threshold was $1) - I really wonder how many people did the same.

It's been 2 hours and I still haven't fully calmed down.

Same - just had some malicious bots running through my platform last week and really thought they found a security hole after all. Even though the amount sounded ridicoulus, I got quite nervous and a very bad feeling when I logged-in AWS and saw that price.

This is embarrassing for Amazon, but I’d take laughably wrong over subtly wrong any day. If the bug made bills 20% higher I probably wouldn’t have queried it.

The should pass a law saying they should have to pay you the amount over the correct bill as compensation; I bet they'll stop making mistakes like this pretty quickly after that

Probably the safest bet is to pay your bill in full to stay in good standing and then get refunded the difference when they revise it down.

I don't want to say this was ever or will ever be a good idea, but the reality of warfare is a lot of the time dudes were just running into an alley and firing off mortars without trying to look or think of what they were shooting at anyway. I doubt the Taliban gave a shit about false positive rates when they were cutting the hands off of anyone who voted. They got the point across either way.

They sent 3 warnings to my email, ok, I understand bugs happen (probably vibe-coded). But they didn't even send any notification that it's a bug. Going to leave AWS after that.
xp84 6 hours ago||
Somehow I highly doubt anyone will leave AWS over this unless their use of AWS is way more low-complexity than the average account.

People make similar pronouncements after every us-east-1 outage makes the news, but I feel like AWS would be going out of business by now if people followed through.

It reminds me of airlines, where after a particularly grueling irregular ops experience, a few dozen people file off the plane swearing "Never again, <airline name>!" but really, we all must know deep down that the airlines are all subject to the same external inciting factors, internal profit motivations, and human imperfection, and thus all pretty equally likely to cause us a bad day or ruined trip. The effort spent to avoid one isn't really worth it.

el_memorioso 5 hours ago|||
Airlines are all subject to a lot of the same factors, but there are unequivocally better and worse performers in terms of on-time arrivals, by a lot. Take a look at the Air Travel Consumer report for details.

One can almost smell the vibes.

This is peanuts compared to a major cybersecurity catastrophe that’s surely in the making.

To give credit to the technology and the people using it - and I’m not being facetious - it’s actually incredible that at the current levels of usage the unprecedented catastrophic event has not yet happened.

Any individual human (or frog, obviously) is getting out of the pot when it gets uncomfortable.

True stupidity requires a group of humans, all sitting in the pot, telling each other how lucky and special they are to have this wonderful pot, getting paranoid about outsiders who might disrupt their god-given pot-dwelling way of life, and mocking anyone who suggests that the pot might be getting a little too warm.

It was the mid 2010s when I sensed a lot of SaaS becoming popular. Just host your ticketing systems, your IT management planes, your security management consoles, your SOC, all off-premises.

I wonder if businesses are thinking of ever swinging back to locally hosted, with the increased hostility of the Internet re: AI, vulnerabilities, DoS, and so on.

gaudystead 5 hours ago|||
I'm sure some businesses are considering moving back to on-prem, but for many, I suspect the cost to find onboard, and pay the SMEs to keep those systems running well enough to not fail due to one reason or another isn't as appetizing to them as the ability to offload that work, along with the legal responsibility.

When something goes wrong, pointing the finger at someone else is far easier for most than pointing it at yourself.

elzbardico 4 hours ago|||
One thing that you need to understand is that the usual business manager absolutely hates depending on technical expertise, and that the modern corporate world is fanatically anti-intellectual.

Vendor lock-in? compliance and security risks? stupid systems that cost the company an arm and a leg? nobody fucking cares.

Now, depending on an 130 IQ Engineer that basically holds the whole enterprise on his head? Anathema!!!!!!! Bus Factor!!!!

Clearing LLMs out of our business infrastructure is going to be a massive undertaking. Though I have a tech background, I work in commercial real estate. We are recently seeing new levels of idiocy from the employees, including real estate brokers with zero tech knowledge "coding" solutions to find sites for clients and blindly trusting the output (which I came to find out was complete bullshit), as well as some who have literally stopped communicating with any of their own language - meaning every interaction they have with anyone not in person is made by an LLM. It's a massive threat to our brand and has got to stop. I can't imagine what companies with thousands or tens of thousands of employees who have really been riding the LLM train are going to have to deal with. This thing is more of a virus that exploits human laziness than actual useful tech.
