Hello,
I am sorry to hear about the issue with your instance i-0c9d6ec62a98addd4.
I have checked the instance and I could see that the underlying physical host, on top of which your instance was hosted, started experiencing hardware related issues at 2019-01-25T16:33:00.000Z. This caused your instance to reboot.
Please note that in the future you can check whether an instance was affected by a hardware related event by checking its 'System Status Checks' [1]. The history of these checks can also be viewed in Amazon CloudWatch by looking at StatusCheckFailed_System metric \[2,3].
Please accept our apologies for the above issue and for any inconvenience caused by it.
I have now checked the instance and I can see that it is back up and running again.
I would like to suggest that you to take a look at the Auto Recovery feature for Amazon EC2. You can create an Amazon CloudWatch alarm that monitors an Amazon EC2 instance and automatically recovers the instance if it becomes impaired due to an underlying hardware failure or a problem that requires AWS involvement to repair. Basically, you can use CloudWatch to set up the alarm which will trigger when the System Status check fails. This alarm can further trigger an EC2 Action like "Recover this instance" \[4,5].
We also advise to our customers to design their application in such a way such that there is no single point of failure in their environment. Please refer to our white paper on Building Fault-Tolerant Applications in the AWS Cloud \[6] for more information.
Please let us know if you need any further help.
