It looks like the forum thread has been updated with the following comment from Luke@AWS > I just looked into your instance a bit further, it does appear this was due to an issue with the underlying host on which your instance resided upon when you encountered the issues today. > I do want to clarify here as our original reply mentioned a scheduled retirement, this was not the case and no notice was sent out because of this. It looks like the original email was incorrect. To add to this though if people rely on advance email notifications with AWS then they are putting at risk their availability. Just because it is on the cloud doesn't insulate you from hardware issues, these need to be planned for. AWS does provide some building blocks to address this (auto-scalaing and load balancers come to mind).
