Lightsail website not working
Public IP: 18.209.227.83
Domain: bbs.exlabnyc.com
My website went down since yesterday morning. I noticed that the CPU utilization rate went up to 100%(I didn't do anything.) 
One of my friends told me all my files on my instance were gone. But if that's the problem, the server should at least give some responses when I ping it right?
Could I be hacked and the hacker deleted all my files? Is that possible?
It sounds like the BBS software you're using went over your burst capacity. If the utilization graphs indicate that you're frequently going over burst capacity, you might solve the issue by using a larger instance size (take a snapshot of your instance and create a new larger instance from the snapshot).
Otherwise, you can look into what's causing your software to use so much CPU to see if you can keep it within your allotted capacity.
