Coinbase announced the restoration of its transaction processing services, which were suspended after a failure in Amazon Web Services (AWS) infrastructure. The issue was caused by failures in some infrastructure components triggered by increased temperatures in the AWS data center in northern Virginia, USA. During the outage, Coinbase put the market into "cancel-only" mode to protect user transactions. In this mode, users could only cancel existing orders, and new buy or sell operations were impossible. The company later gradually resumed trading services, first stabilizing the market in "auction" mode, and then returning it to normal trading mode. Coinbase stated that systems are usually designed to be resilient to failures that may occur in a single AWS availability zone. However, in this recent incident, simultaneous problems in multiple availability zones led to prolonged outages of core computing services.
