Amazon Web Services (AWS), the cloud computing giant responsible for hosting a vast segment of the internet, experienced a significant outage on Monday that lasted for several hours, wreaking havoc on numerous major websites and applications. This disruption had far-reaching impacts, affecting everything from banking and social media platforms to airline booking systems and online shopping services. Millions of users, particularly those commuting on the US East Coast, found themselves unable to access critical applications, such as mobile coffee ordering, as the outage unfolded.
The incident highlighted the vulnerability of the internet’s infrastructure, even brief disruptions can ripple through the digital landscape, reminding users of the extensive dependence on cloud services. While Amazon and other cloud service providers generally maintain a robust operational framework, the complexity of the internet can reveal weaknesses, often hinging on the reliability of interconnected services.
Though the specific cause of the outage remains unclear, the problems appeared tied to a service responsible for converting user-friendly web addresses into corresponding IP addresses, which renders massive databases hosted by AWS unreadable for many companies. Experts noted that previous outages of a similar nature had resulted from various types of errors—ranging from faulty updates and inadvertent code injections to compatibility issues with third-party software. Although rare, incidents such as cable cuts, cyberattacks, or denial of service attacks can also affect server performance.
Rob Jardin, the chief digital officer at cybersecurity firm NymVPN, stated that there were “no signs” suggesting a cyberattack, indicating that the issue likely stemmed from a technical fault within one of Amazon’s primary data centers. He emphasized the paradox of today’s internet, which was designed to be decentralized and resilient, but now increasingly relies on a handful of cloud regions. When one region faces a technical issue, the consequences can be profound and widespread.
Experts like Mike Chapple, a cybersecurity specialist and IT professor at the University of Notre Dame, explained that major disruptions of this nature are noteworthy because of their impact on so many services simultaneously. While AWS has occasionally faced outages, the last notable one occurred in 2021, making Monday’s incident stand out.
This tense moment in digital history recalls previous large-scale outages, such as the 2024 CrowdStrike software glitch that crippled vast portions of the internet, inciting major financial losses and operational hiccups worldwide. Last year, AT&T experienced several network failures, including one that lasted for 11 hours, significantly impeding the work of gig economy workers relying on connectivity.
AWS was born from Amazon’s initial need for additional server capacity during peak traffic periods. Over the years, the company adapted this resource into a platform that supports numerous organizations’ online services, housing critical data like customer information in its databases, such as DynamoDB.
When users found themselves unable to access data previously housed within DynamoDB, it was due to an issue with the Domain Name System (DNS)—often described as the internet’s “phone book.” The DNS encountered complications that rendered the stored data inaccessible for several hours. Chapple likened the experience to a collective moment of “temporary amnesia” for parts of the internet.
While the DNS issue persisted for only a few hours, by 6:35 AM ET, Amazon had resolved the problem and advised customers to clear their caches to expedite service restoration. However, the outage continued to affect various other AWS services, such as EC2, a virtual server solution many companies employ for their applications.
As the dust settled from this significant disruption, Amazon is expected to conduct an in-depth analysis to determine what went wrong with its DNS system in the coming days, aiming to mitigate such risks in the future.
