Evidence

+  * If impairment is detected on an UltraServer Capacity Block, you are notified but generally your instances are not terminated 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 your support case is received, you are notified when remediation is complete and you can relaunch instances onto your UltraServer Capacity Block.
