My instance was running fine and this morning I was able to access a Ruby on Rails app hosted on it. An hour later I suddenly wasn't able to access my site, my SSH connection attempts were refused and the server wasn't even responding to
ping. I didn't change anything on my system during that hour and reboots aren't fixing it.
I've never had any problems connecting or pinging the system before.
Can someone please help? This is on my production system!
