CME Group Derivatives Trading Stall After AWS Northern Virginia Outage
An AWS outage Thursday in the Northern Virginia data center zone disrupted CME Group’s derivatives trading and market data feeds alongside Coinbase for over two hours. By midday, CME rerouted systems to alternative zones, restoring processing and clearing functions, though latency persisted as teams investigated the root cause.
1. AWS Outage in Northern Virginia
Thursday morning, one of AWS’s Northern Virginia data center availability zones experienced a service interruption beginning around 10:30 a.m. ET. The outage halted connectivity for clients relying on that zone, including major trading platforms.
2. Impact on CME Trading
CME Group’s derivatives trading engines and real-time market data feeds paused for over two hours, suspending new order entries and delaying trade confirmations. Participants reported delayed trade execution and temporary suspension of certain electronic clearing functions.
3. Recovery and Investigation
By midday, CME engineers had rerouted systems to unaffected AWS zones, resuming order processing and clearing operations. Some latency issues remained as infrastructure teams worked to identify the root cause, with full normalization expected later in the day.
