I've set up a game server on Amazon EC2. However it is often going offline for ~10 minutes, failing a status check.
Instance reachability check failed at January 31, 2016 at 8:10:00 PM UTC+1 (4 minutes ago)
When it gets back online, it looks like it was just shut off from the internet. I can imagine it can be DDoS attacks from competing servers, but I am not sure how to come to a conclusion about that.
Does anyone have any clue what can cause this? Or how I can debug it?
