You mentioned that the website didn't start back up. Did your droplet begin responding to ping requests? Are you able to reach it by SSH? If not can you log in via the console in the control panel?
Once you get access to your server you can try restarting your web server to see if that brings your site back online or displays an error that will help in tracking down the issue. Since you haven't provided any details on either the operating system or the web server you are running I've provided the commands for the two most common web servers below:
For Apache on Ubuntu/Debian:
service apache2 restart
For Apache on CentOS/Fedora
service httpd restart
For Nginx:
service nginx restart
