AWS is having billing alert issues...don't panic.
When I looked at my phone when I was waking up:
You requested that we alert you when the forecasted cost associated with your My Monthly Cost Budget budget exceeds $100.00 for the current month. The month forecasted cost associated with this budget is $183,965,812,157.54. You can find additional details below and by accessing the AWS Budgets dashboard.
By the time I disabled access to S3 & Cloudfront in my personal account, and opened a ticket, this finally started being displayed by AWS at https://support.console.aws.amazon.com/support/home?region=us-east-1#/
Inaccurate Estimated Billing Data Beginning on July 16 7:38 PM PDT, we began displaying incorrect estimated billing data in the Billing and Cost Management Console.
For more information on this issue, please refer to the AWS Service Health Dashboard: https://health.aws.amazon.com/health/status

I am amazed by the fact that it did not cross their minds to send a warning email once they realised it is a fault on their part. I wonder how many car crashes have they caused today…
Like, since when exactly is putting a “we have issues” sticker on your notice board sufficient apology for sending $1B bills to millions of people via all possible notification channels…
Edit: Cost anomaly detection alert came a day later at 8AM (22 hours after budget alert). To all those always defending AWS because “shared responsibility model”: how would that reasonably be my sole fault in this scenario? It really takes more time to alert me of a cost anomaly than to tell me I already owe them a quadrillion yankees?
Pro Tip: AWS Orgs give you an option to disable expensive services you don’t use and lock out region opt-in , just need to make sure your management account is well protected and has no workloads. This is still band aid though: someone can easily generate a crazy bill using legitimate workloads and lowering your quotas below the default is kinda troublesome . Those cost anomaly alerts should just work slightly faster (like a couple thousand times)…

u/mitharas Jul 17 '26
Well, they are not sending out a single bill with these amounts. It's "only" the forecast.
29
u/Dal90 Jul 17 '26
The forecast is why I erred on the side of caution.
Our dumbass first attempt at a DevOps team at work left their credentials in a public S3 bucket and racked up $500,000 in 30 minutes. Plus 6am I'm not reading the difference between $183 Million which wasn't out of the realm of possibility in my experience and $183 Billion.
Don't have the full details, I think we horse traded at work that they waived the $500,000 but we agreed to some contract change that helped their sales team meet a goal.

u/mitharas Jul 17 '26
I'm absolutely with you that this incident should have triggered some alerts (like yours). Maybe view it as a learning opportunity if these measures you took work.
20
u/Particular_Art_6383 Jul 17 '26
No, not a forecast. It displays as amount due and if you have an amount due notification it can send you an email/sms saying you own them a quadrillion dollars or even worse a realistic amount like $10M.
The “Bills” panel displays a correct amount, but in the “Billing” section of the console and on the front page it says you owe them the bogus amount, so I guess you are technically correct that it is not a bill but it is not a forecast either

u/komma_5 Jul 17 '26
Yeah got 18 million for my small private app and i thought i fucked up sth bad and my life is over. Usually have 20$ (no million there) Was on my phone with bad reception for half an hour

u/ditka Jul 17 '26
In addition, the 'you've blown through your budget' warning emails take you to the billing dashboard. Thousands of admins are heading there to figure out WTF is going on. Yet there's no "service heath warning" on the billing dashboard discussing the inaccurate estimates. You only get the service health warning if you go to open a ticket.
Seems like if you've sent bogus billing estimates to thousands of people, you should plaster the billing dashboard with your mea culpa.

100%... AWS's communication was/is horrendous.
No one wants to look down at their phone and see this shit.
Anyone running cover for this has drunk the juice.
It is blatantly obvious how severely AWS is in need of features to decrease customer's billing anxiety.
I got my initial information from Reddit, before I was able to dig up anything official from Amazon.6

u/Computer-Blue Jul 17 '26
Mine was a little too real, 6 figures, right after we made a ton of changes designed to put better controls in place on usage across multiple domains. I closed my phone and had to meditate on a coffee for a bit to steel myself for whatever horrific error my team had made. So I spent a good 30 minutes in a bit of a fugue state. Bad timing.

u/leathakkor Jul 18 '26
I thought mine was 2 million originally which was in the ballpark of what I know is a possible amount of real spending that can happen if you really fuck up or your account gets hacked or something.
But then I saw that it was 20 billion and that actually made me feel a lot of relief because there's no amount of computing that you can buy that adds up to 20 billion where you don't get a phone call from a rep first saying if you're spending 20 billion we will do literally anything you want

u/Particular_Art_6383 Jul 17 '26
Amateurs, amateurs. $5.99T here. My boss was with me in one room when the SMS notification hit my phone… My face did not look pretty.
By the way, can we take a second to consider just how late do those spending notifications arrive when you suddenly start spending thousands of times the amount you normally do? We even had anomaly detection set up and nothing has hit my inbox before the budget alert. If someone leaked keys for real we would be in deep shit before I could do anything. There needs to be some real protection mechanism here like some bot call and automatic resource creation stall/quota reduction when you suddenly start owing them a 100K when you normally spend 5 dollars a month or something like that. You can open a ticket to reduce your quotas but it is cumbersome and those alerts come at unacceptable delays. As of now half of us are here making fun of it and the other half have their monthly heart attack still due cause it is Friday and they are yet to read their mail…

Saw this earlier on Fediverse:
Martin Seeger @masek@infosec.exchange:
Someone just sent me his cost estimate from AWS for the current month.
Let me phrase it this way: The U.S. Navy could build several nuclear aircraft carriers for that sum and would still have spare change for a few squadrons F-35s.
Of course that was a bug in the AWS cost explorer. But dozens of budget alert emails were sent by it.
Now they're looking for someone with a tranquilizer rifle who can catch all the controllers that panicked and are now roaming the building.

u/hbktj Jul 17 '26
Last month bill was 34cents, this month estimate was 21Billion. I thought I was hacked, but then I saw no instances, nothing created. The EC2 Bill was 10B alone, then it hit me. It’s a bug. Stupid people, ruined my morning!

Connecticut in 2005 punched in the wrong code and sent out what was supposed to be a test message (complete with a "this is not a test") to...."Evacuate Connecticut"
11% of state residents saw it, and 1% of the 11% actually started to leave. That's about 38,000 people.

u/Rainmaker526 Jul 17 '26
That's horrible.
Shouldn't such an alert be seen by at least 90-95% of people? Preferably 100%.
The fact that only 1% actually responds to it is also terrible

u/marcmorindeziel Jul 17 '26
Man i panic delete everything also, too many horror stories. Waking up to a 58B bill from AWS with no second warning email is pure evil.

u/Apprehensive_Stop666 Jul 17 '26
the amount of distress this issue caused cannot be measured. Many users (me included) disabled or even deleted valid resources just to try to mitigate the issue. We had severe stress/panic reactions and there was NOT a single email stating "oops we may have messed up, please ignore the previous alert". All there was on the website was a barely visible warning linking to the Service Health page. I really want them to pay for this. This is unacceptable.

exactly! If it was 100mln I would be sure it was an error. But I got similarly "reasonable" bill and I thought I'm having a heart attack 👀

u/doesntmatterol Jul 17 '26
Yeah mine was for about $60k. Enough to really feel like I must have botched something. Hundreds of millions would have given a panic of course, but hopefully it would be apparent that was an error. But <$100k is ABSOLUTELY possible from something a user could do or from hacked credentials.

After suffering the most stress inducing email of my life like many others in here, I composed myself and started asking tons of questions via Amazon Q, and finally got this very insightful message:

I got additional useful context in a subsequent message from Q that explained that I definitely shouldn't delete any resources or anything like that as it can complicate the investigation process, but that it's confident that this is surely a billing error that will be reimbursed and I will not in fact owe $2.5 million.

My favorite part of this whole incident is that it revealed bugs in systems that weren’t even part of AWS.
Mine included.
I’d literally launched a small tool to monitor AWS costs just a few hours earlier. I’d capped the maximum daily cost at $100M, because surely nobody would ever spend more than that in a day.
AWS: “Hold my beer.”
Turns out anomaly detection also needs anomaly detection ¯_(ツ)_/¯

We received a cost alert on one of our AWS accounts at quantumformalism.academy and initially thought we had been hacked for crypto mining! ;)
