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.

Trump signs an executive order requiring a review of restrictions on cryptocurrency companies accessing the U.S. payment system

On Tuesday local time, U.S. President Trump signed an executive order requiring the federal government and the Federal Reserve to review the existing regulatory framework to promote deeper integration of digital assets and financial technology into traditional financial services and payment systems. The executive order mandates U.S. financial regulators to review current rules within the next three months and identify any "unreasonable barriers" to cooperation between fintech companies and federally regulated financial institutions. Within six months, regulators must also take measures to encourage financial innovation. Among other things, the order specifically requires the Federal Reserve to reassess the eligibility of uninsured deposit institutions and non-bank financial companies for payment accounts and payment services.The document also requests the 12 regional Federal Reserve Banks to study whether they can independently open payment accounts to relevant institutions without relying on the approval of the Federal Reserve Board. Analysts believe this policy may benefit special purpose deposit institutions in Wyoming and similar structures for cryptocurrency companies. Previously, Kraken's Wyoming SPDI had obtained a limited version of "master account" authority from the Kansas Federal Reserve, and other cryptocurrency institutions are also seeking similar qualifications. Reports indicate that the Federal Reserve is currently also studying a more formal "streamlined master account" mechanism and had announced related proposals last December.

The Korean FSC is reviewing whether Hana Bank's acquisition of Dunamu shares violates regulatory rules

According to iNews24, the Financial Services Commission (FSC) of South Korea is reviewing whether Hana Bank's acquisition of Dunamu shares violates the "separation of finance and virtual assets" regulatory rules. The virtual assets department of the Financial Services Commission stated that Hana Bank indirectly holds shares in Dunamu through its acquisition of Kakao Investment shares, which is essentially an investment in a virtual asset exchange and will be examined under the same standards.Since 2017, the South Korean government has prohibited financial institutions from holding, purchasing virtual assets, or making equity investments through administrative guidance. If a violation occurs, Hana Bank may not be able to complete the transaction. Future Asset Consulting is advancing the acquisition of Kobit's operating rights, and Korea Investment & Securities is also taking a cautious approach. Hana Bank previously announced the acquisition of a 6.55% stake in Dunamu but did not consult with the authorities beforehand.Currently, the "separation of finance and virtual assets" regulation has not yet been codified into law, and it is uncertain whether related provisions will be included in the digital asset bill. Legislative discussions may advance after the National Assembly reconvenes in September at the earliest.
