Q: How does EC2 perform maintenance?
AWS regularly performs routine hardware, power, and network maintenance with minimal disruption across all EC2 instance types. To achieve this we employ a combination of tools and methods across the entire AWS Global infrastructure, such as redundant and concurrently maintainable systems, as well as live system updates and migration.

To achieve this we employ a combination of tools and methods across the entire AWS Global infrastructure, such as redundant and concurrently maintainable systems, as well as live system updates and migration. And yet, I keep getting almost every weeks emails like this: "EC2 has detected degradation of the underlying hardware hosting your Amazon EC2 instance (instance-ID: i-xxxxxxx) associated with your AWS account (AWS Account ID: NNNNN) in the eu-west-1 region. Due to this degradation your instance could already be unreachable. We will stop your instance after 2022-09-21 16:00:00 UTC" And we don't have tens of thousands of VMs in that region, just around 1k.
