AWS updated its EC2 pricing and reservation terms, effective July 17, 2026. The company introduced new restrictions on On-Demand Capacity Reservations, prohibiting resale to third parties and reserving the right to cancel purchases or terminate instances if resale is suspected. AWS also revised termination windows for Capacity Blocks for ML, extending the notice-free termination period from 30 minutes to 60 minutes for UltraServer instance types. Additionally, AWS rebranded its Amazon Sidewalk qualification program from 'Works with Amazon Sidewalk' to 'On Amazon Sidewalk' and simplified trademark licensing requirements for qualified devices.
Aws customers: You cannot sell your capacity reservations to someone else, and AWS can cancel your purchase or shut down your instances if it thinks you are trying to.
The updated terms establish new restrictions on how AWS customers can use On-Demand Capacity Reservations. Customers may no longer resell reservations to third parties, and AWS reserves the right to cancel purchases or terminate instances if it suspects resale activity. For customers using Capacity Blocks for ML with UltraServer instance types, the termination window without notice has been extended from 30 minutes to 60 minutes, increasing the period during which instances may be terminated without advance warning. These changes reduce flexibility in reservation management and increase operational risk for workloads relying on Capacity Blocks.
→ Review current EC2 On-Demand Capacity Reservation holdings to identify any existing resale arrangements that must be discontinued.
→ Update workload scheduling and failover procedures for Capacity Blocks using UltraServer instances to account for the extended 60-minute termination window.
