Coinbase Outage Disrupts Crypto Trading and Transfers Amid Amazon Service Failure

Coinbase users faced hours of service disruptions late Thursday and into early Friday after failures tied to Amazon Web Services infrastructure disrupted core trading systems, the cryptocurrency exchange said.

In a post on X Friday morning, Coinbase said the outage began around 8 p.m. ET on Thursday afternoon, after its systems detected elevated error rates across multiple services.

“Around 8 p.m. ET, Coinbase systems detected elevated error rates across multiple services, which the company traced to failures in AWS Availability Zone use1-az4 in the US-EAST-1 region,” Coinbase wrote.

The outage follows another AWS-related disruption in October that temporarily knocked Coinbase and Robinhood offline, and prevented some users from accessing their accounts or executing trades.

Coinbase said its systems are designed to recover from a single availability zone outage. In this case, however, the company said failures affected multiple AWS zones, causing what it described as an “extended outage” of core trading services while AWS worked to restore temperature controls and other managed services.

Amazon disputed Coinbase’s description of the outage, telling Decrypt that only a single availability zone was ultimately impacted.

Users reported problems accessing the Coinbase app, transferring funds, and executing trades. Downdetector reports spiked around 6 p.m. ET and remained elevated overnight before declining Friday morning. About 33% of reports involved fund transfers, another 33% involved trading issues, and roughly 29% were related to the Coinbase mobile app.

Coinbase said the primary issue has been resolved, and directed users with account-related questions to Coinbase Support.

“Our team will conduct a full analysis,” Coinbase wrote in its X post. “Details may change as our investigation progresses and more information is received from AWS’s official retrospective, once published.”

Coinbase did not immediately respond to a request for comment by Decrypt.

The outage comes as Coinbase pushes deeper into cloud-based AI and stablecoin infrastructure through partnerships with companies including Amazon Web Services and Stripe, while also restructuring around what CEO Brian Armstrong has described as an AI-first operating model.

“AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era,” Armstrong wrote on X. “This is a new way of working, and we need to leverage AI across every facet of our jobs.”
