i'm having trouble with an EC2 instance experiencing a long period (several hours) of downtime every day
- instance type: t1.micro
- availability zone: ap-southeast-2a
- security groups: allow all ICMP, ssh (22) and http (80)
- AMI: based on Ubuntu Server 12.04.3 LTS Server - ami-3d128f07 (64-bit)
- software: openssh, nginx, gunicorn, django
cloudwatch metrics all look good: cpu, memory, disk, etc. and ec2 status check is 2/2 checks passed
i can still ping the machine however i can't reach it over http or ssh
once i can login to ssh (probably after a restart), where would be the best place (log, etc.) to check what is going on during those periods of downtime? everything in the syslog seems fine and dandy!
