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.

October 20, 2025Non-Tech Here, Curious on AWS Outage Affecting Multiple Sites All Day
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. More on reddit.com
