Coinbase CEO Brian Armstrong revealed that the exchange experienced a service outage due to simultaneous cooling failures at an AWS data center, resulting in overheating. The incident highlighted limitations in the exchange’s architecture, which prioritizes low latency and colocated clients. Armstrong said the team will review the system design to reduce future downtime. The event adds to ongoing concerns in the crypto exchange space, as users remain cautious about potential hacking risks. He thanked AWS and Coinbase staff for resolving the issue overnight.

Huoxing Finance reports that Coinbase CEO Brian Armstrong posted on X that Coinbase experienced a service outage yesterday, which is unacceptable. The root cause was the simultaneous failure of multiple cooling units in an AWS data center, causing a server room to overheat. Most of Coinbase’s systems are designed with redundancy to handle the failure of a single availability zone, and they operated normally last night. However, the centralized exchange was affected because its architecture was specially optimized for low latency and customer colocation, making it difficult to simultaneously achieve availability zone-level fault tolerance.While building fault tolerance against availability zone failures introduces latency and disrupts customer colocation, the team will reevaluate these trade-offs to ensure that, when a zone switch is necessary, the duration of downtime is significantly reduced. He thanked the AWS and Coinbase teams who worked through the night to restore services and pledged to release a detailed technical explanation soon.
