What caused the AWS outage - and why did it make the internet fall apart?
But on Monday, something very mundane went very wrong: a common kind of outage known as a Domain Name System (DNS) error. People who work in the tech industry will be rolling their eyes right now. ... When someone taps an app or clicks a link, their device is essentially sending a request to be connected to that service. DNS is supposed to act like a map, and on Monday, AWS lost its bearings – platforms like Snapchat, Canva and HMRC were all still there but it couldn't see where they were to direct traffic to them.

r/aws on Reddit: Worldwide AWS Outage?
October 20, 2025 -
It all started when I was trying to by something from Mercado Livre, one of the biggest portals here in Brazil. Couldn´t load account specifics, cart or change other profile settings, like adding a credit card.
So I decided to buy it from Amazon, same behavior. Went to Brazil's Down Detector and it seems to me that all services that rely on AWS are failing.
Went to the the US Down Detector site and I am seeing what seems to be the same cascading failure right now.
Any1 facing similar problems?

r/aws on Reddit: Non-Tech Here, Curious on AWS Outage Affecting Multiple Sites All Day
October 20, 2025 -
Hi All,
As title suggests, I just popped in as a non-technical non-user aside from knowing that Flickr is down and has been all day long now, and apparently many other large sites, Reddit included.
Anyone here know the real deal and what's what and can explain it to me like I'm 5?

When a website has to handle people (users) going to the website and making use of the services on it that requires computers actually processing those decisions and actions by the users. In the past businesses would do this themselves by having dedicated computers (servers) handle that processing. They would have these computers on-premises and have their own IT handle expansion and maintenance of those servers. Nowadays most of the businesses and websites on the internet no longer have their own computers because of the time and investment needed to manage it and just rent the usage of computers from Amazon, Microsoft, Google, or whatever hosting they choose to use. AWS normally has a 99.999% availability meaning that it normally has like a 5 minute total downtime for the entire year and for the most part they're very consistent about maintaining that availability. When it goes down that means the businesses that rent the usage from Amazon don't have any way to actually process incoming requests to their website and don't have a backup in place (because this usually does not happen) meaning that the websites go down. Huge amounts of the internet including the sites you mentioned use Amazon to host their sites and so when it goes down they also do.

In Flickr terms, imagine AWS as a giant version of Flickr. Not just for photos, but for everything. Apps, websites, and data. Companies use AWS to store their files and run their services, just like you upload photos to Flickr. AWS is built with a lot of backups and redundancies. It keeps copies of things in multiple “regions” which is just different datacenters across the world. Normally, if one has a problem, another can pick up the slack. But sometimes, very rarely, a major issue hits an entire region. When that happens, every app or service that depends on that specific region can go down. And because some AWS tools depend on other AWS tools (even across regions) it can trigger a domino effect. One outage cascades into others, and suddenly you got a big ol' ball of clusterfuck.
