"We are reaching out to inform you that we will be retiring EC2-Classic on August 15, 2022. This message contains important information about the retirement and steps to take before the retirement date

How does this impact you? Your AWS account currently has EC2-Classic enabled for EU-WEST-1 Region"..

To be fair, "EC2-Classic is a flat network that we launched with EC2 in the summer of 2006", so I'm not complaining, but thought it was an interesting counterpoint.
