• Coinbase reported several service disruptions across its platform, leading to an extended outage for users.
• The outage resulted from AWS failures in the US East-1 region, which affected multiple zones that impacted Coinbase's trading services.
• The firm confirmed that the primary issue has been resolved, with services expected to resume normal function.

Coinbase said Friday that users experienced an extended outage across its platform after service failures within Amazon Web Services (AWS) disrupted critical trading infrastructure in the US East region.

Coinbase stated in an X post that the disruption began around 8 PM ET on Thursday, when its systems detected elevated error rates affecting multiple services across the exchange. The company later traced the issue to failures within the AWS Availability Zone use1-az4 in the US-EAST-1 region.

The exchange noted that its systems are designed to remain operational during a single-zone outage and are built to recover quickly under those conditions. However, the incident became more severe after failures spread across multiple AWS zones, resulting in a prolonged disruption across its trading services.

"We observed failures impacting multiple AWS zones, which caused an extended outage of core trading services," Coinbase wrote.

The outage temporarily affected users attempting to access trading functions and other services on the platform while AWS engineers worked to restore temperature controls.

Coinbase did not disclose how many users were impacted or whether any transactions were delayed during the outage. The company said the "primary issue" has now been fully resolved, with services expected to return to normal operation.

The firm confirmed that the primary issue has now been fully resolved and said platform services are expected to resume normal operations. Coinbase added that its internal teams will conduct a full review of the outage and noted that additional details could emerge once AWS publishes its official retrospective on the incident.

The disruption comes a day after Coinbase released its first-quarter earnings report, which showed weaker financial performance amid declining crypto market activity. The exchange posted a net loss of $394.1 million for the quarter ended March 31, while total revenue fell to $1.4 billion amid slowing trading volumes.

Despite softer transaction revenue, Coinbase highlighted continued growth in subscription and services revenue, stablecoin-related income and derivatives trading activity. 

The company also emphasized ongoing diversification efforts beyond spot trading, including expansion of its Base blockchain ecosystem and tokenized asset offerings.
