Coinbase Down for Hours Due to AWS-Related Outage

Coinbase, the largest cryptocurrency exchange in North America, has been inaccessible and unusable since around 9 AM Asia time, lasting for over seven hours by 4 PM. During this period, some users repeatedly encountered Cloudflare verification when accessing the page, and subsequent feedback indicated that the service restoration was not synchronized.

Coinbase Support's latest response on X stated that all markets on the Coinbase Exchange have reopened for trading. However, based on user feedback, the malfunction did not end simultaneously across all ports, with some people still reporting that they cannot access the platform, cannot trade, or are waiting for Solana transfers to be credited.

The outage first appeared in the on-chain transaction and receipt process. Coinbase's status page indicated that there were delays in sending and receiving for ALEO and Solana networks on May 7, with buying, selling, fiat currency recharges, and withdrawals still unaffected at the time. Subsequently, the issue expanded from a single network delay to a decline in the platform's trading capabilities. Coinbase stated that some customers might not be able to trade through web and mobile, attributing the cause to a rise in temperature in the us1-az4 availability zone of the AWS US-EAST-1 region.

Throughout the recovery process, it became evident that this was not a simple page malfunction. Coinbase initially put all markets into "Cancel Only" mode, allowing users to cancel existing orders but not accepting new market or limit orders to reduce the risk of transaction mismatches during the recovery process.Subsequently, markets entered a call auction mode. Users could submit limit orders and view reference opening prices, but matching would not occur for at least 10 minutes, and cross-orders would be filled at the opening price after the auction period ended.
