NEW YORK, Jan 19, 2026, 09:41 EST — Market closed.
- AWS reported a disruption on Sunday impacting DynamoDB and several other services in its US-EAST-1 region.
- Amazon shares ended Friday’s session up 0.39%, closing at $239.12. U.S. markets remained closed Monday for Martin Luther King, Jr. Day.
- Investors are eyeing AWS updates as trading resumes Tuesday, with Amazon’s upcoming earnings also in focus.
Amazon.com, Inc. (AMZN.O) has returned to traders’ radars after Amazon Web Services reported it’s probing higher error rates and latency spikes in its DynamoDB database service within the US-EAST-1 region. AWS confirmed that other services on its platform are also impacted.
U.S. stock markets will be closed Monday in observance of Martin Luther King, Jr. Day, meaning investors won’t get a chance to react until trading resumes Tuesday. The timing is notable, given AWS’s reliability and capacity are currently hot topics among those questioning Amazon.
Amazon shares closed Friday at $239.12, up 0.39%, after fluctuating between $236.41 and $239.57. Volume hit 45.89 million shares. The S&P 500 and Nasdaq each dipped roughly 0.06% during the session, according to Investing.com data.
Later, AWS pointed to a “DNS resolution” problem affecting the DynamoDB API endpoint in US-EAST-1. DNS acts like the internet’s address book—when it can’t map a service name to the correct network location, apps can hang even if the servers themselves are up and running. AWS Health
The bottom line is clear: AWS keeps the lights on. In Q3, AWS sales jumped 20% year-over-year to $33 billion, with operating income hitting $11.4 billion, Amazon reported. CEO Andy Jassy highlighted that AWS is “growing at a pace we haven’t seen since 2022.” Amazon
Cloud outages tend to rattle both customers and investors, even if they don’t last long. Back in October, Amazon announced that AWS was back to normal following an outage that affected users around the globe, Reuters reported.
Amazon is set to release its quarterly earnings on Feb. 5, per Nasdaq’s earnings calendar. Investors will zero in on AWS growth, profit margins, and how management addresses AI-driven demand.
Service health is just one factor here. Amazon’s ramp-up in AI infrastructure spending has investors on edge, especially as capital expenses outpace profit gains in the near term.
AWS is locked in a fierce battle for enterprise cloud dollars, as Microsoft and Alphabet aggressively target the same workloads. When AWS’s growth slows or expenses rise, Amazon’s stock often takes a hit — and that volatility remains a key factor.
Investors will be watching closely when U.S. markets open Tuesday for any new AWS updates or clues about customer fallout. After that, all eyes shift to Amazon’s earnings report and conference call, set for Feb. 5.
