+  * If we detect impairment impacting an UltraServer Capacity Block, we will notify you but generally will not take action to terminate your instances on the Capacity Block. This is to minimize unintended disruption to your workloads. You can continue using the UltraServer Capacity Block as is after receiving this notification or request remediation by terminating all instances on the capacity block and submitting an AWS support case. After we receive your support case, we will notify you when we have completed remediation and you can relaunch instances onto your UltraServer Capacity Block.
