Coinbase reviews the May outage incident: AWS cascading failure exposes architectural risks

Coinbase released a retrospective report on the large-scale service interruption event on May 7, 2026.The outage lasted approximately 8 hours, with full recovery taking about 12 hours. During this time, trading, deposits, withdrawals, and most core services were unavailable or severely degraded. Coinbase stated that the outage was caused by multiple cooling units failing simultaneously in the cooling system of a data center in one availability zone (use1-az4) in the AWS us-east-1 region, triggering cabinet thermal protection shutdowns, which led to EC2 instances and EBS volumes going offline, affecting multiple internet services.During the recovery process, the Coinbase trading matching engine lost quorum due to the cluster architecture deployed in a single AWS data center losing most nodes. It required urgent code adjustments and the reconstruction of a new node group to restore operation, gradually restarting market trading during the recovery.Additionally, the AWS-managed Kafka (MSK) service experienced control plane failures, preventing the automatic re-election of partition leaders, further blocking quotes, fees, and some settlement and data flow systems, which expanded the overall impact.After manual partition migration in collaboration with the AWS engineering team, the system gradually returned to normal. Coinbase stated that this incident exposed its shortcomings in cross-availability zone automatic switching capabilities and disaster recovery for managed middleware. The company will upgrade its cross-region hot backup architecture, strengthen regular failure drills, and migrate the Kafka system from dual availability zones to a three availability zone deployment, while also working with AWS to advance root cause fixes and improvements.

Viewpoint: Strategy's preferred stock debt amounts to 15 billion dollars, facing pressure to sell BTC

According to Cointelegraph, Arca Chief Investment Officer Jeff Dorman stated that Strategy's current approximately $15 billion preferred stock financing structure has become "unmanageable." He pointed out that these preferred stocks require about $1.5 billion in dividends each year, and with the ongoing volatility in Bitcoin prices, this structure is becoming increasingly difficult to maintain.Strategy's financing model is based on the premise that "BTC will continue to rise significantly." Although the company previously alleviated short-term default risks by issuing additional shares, its decision to repurchase bonds maturing in 2029 is perplexing. He indicated that Strategy may ultimately have only two options: sell BTC to pay preferred stock dividends or stop paying dividends, both of which would have significant impacts on the company and investors.Meanwhile, Strategy CEO Phong Le stated in an interview with CNBC that the company "may sell Bitcoin" at some point in the future, but overall will continue to increase its BTC holdings and enhance the amount of BTC corresponding to each share.Polymarket data shows that the market now estimates the probability of Strategy selling some BTC by the end of 2026 has risen to about 90%. As of now, Strategy holds a total of 843,738 BTC, with a total cost of approximately $63.87 billion and an average purchase price of about $75,700.
