What Can AWS Cloud Outages Teach the Telecoms Sector?

An ongoing Amazon Web Services (AWS) disruption affecting millions highlights a critical vulnerability for the telecommunications sector as digital infrastructure shows its reliance on fragile foundations.

The outage at Amazon's primary US-EAST-1 Region is creating widespread issues for a wide array of websites and applications that depend on its services.

In a statement, AWS confirmed the problem: “We can confirm major error rates for requests made to the DynamoDB endpoint in the US-EAST-1 Region. This issue also affects other AWS Services in the US-EAST-1 Region. During this time, customers may be unable to create or update Support Cases. Engineers were immediately engaged and are actively working on both mitigating the issue and fully understanding the root cause.”

The disruption stems from Amazon's North Virginia data centres, impacting core services like DynamoDB and EC2.

These services provide the database and computing power that thousands of companies, including telecommunications operators and their partners, rent to power their applications.

When these foundational elements fail, the ripple effect is immediate, impacting everything from enterprise communication platforms to customer-facing financial applications.

Cloud instability and service disruption

This event could be seen as a reminder of a reality in cloud computing, the infrastructure supporting many digital services is more delicate than many presume.

The list of affected services shows the breadth of the impact, with users unable to access tools such as Slack, Zoom and monday.com alongside services from companies like Vodafone, Barclays and Lloyds Bank.

This dependency creates a single point of failure that can disrupt business continuity for telecoms and their enterprise clients alike.

This is not the first instance of an AWS outage causing widespread disruption.

AWS has been at the centre of several major outages over the years. In 2012, a 20-hour Christmas Eve outage led to a partial failure of Netflix's streaming service.

A similar issue occurred in December 2021, creating problems for Amazon's retail customers during the peak festive shopping period.

In June of last year, an incident with AWS Lambda affected major organisations like the Associated Press.

A pattern of platform vulnerability

The issue of cloud reliability is not exclusive to AWS. Competitors such as Microsoft Azure have also experienced substantial downtime.

In January 2023, a network issue with Microsoft Azure resulted in an outage for Teams 365 and Outlook.

Microsoft also faced a 'leap year' bug in 2012 when a coding error prevented its platform from generating new security certificates.

Another outage in July 2023 left millions without email access for 19 hours, showing how downtime costs extend beyond inconvenience, particularly in regulated sectors.

“When one of the major cloud platforms goes down, it reminds everyone how interconnected modern business systems have become,” explains George Foley, Technical Advisor at ESET Ireland, a subsidiary of global software company ESET.

He adds: “Even if your own website or app isn’t hosted on AWS, there’s a good chance something you use from your CRM to your payment processor is. Outages like this highlight the importance of having resilience plans in place, including backups and alternative routes for essential data and services.”

The financial cost of cloud dependency

Internet disruptions can inflict billions of dollars in annual losses through their impact on revenue streams, productivity and brand reputation.

Major global outages have been known to cause individual costs exceeding a billion dollars, while mid-sized enterprises can lose thousands for every minute their systems are offline.

According to a 2024 survey, 76% of global respondents run applications on AWS and 48% of developers use its services.

The fact that AWS also powers more than 90% of Fortune 100 companies could suggest that the question is not whether outages will occur but rather the scale of their impact when they do.

For telecommunications leaders, balancing the benefits of cloud adoption with the risk of service disruption remains a primary operational challenge.
