I received an e-mail last week with the following:
We have important news about your account. EC2 has detected degradation of the underlying hardware hosting one or more of your Amazon EC2 instances in the eu-west-1 region. Due to this degradation, your instance(s) could already be unreachable. Running instances will be stopped or terminated after 12:00AM UTC on 2015-12-01. The affected instances are listed below:
i-xxxxxxxx
After some Googling, I came across this - AWS instance scheduled for retirement - What is simplest resolution? - which suggested that I needed to reboot the EC2 to provision it to new hardware.
I did that over the weekend but this morning our client is reporting that DB data is missing. Almost like the server has been restored to an earlier backup. Is that possible?
