I ran the Glasspar Boat Owners Association web site for 20 years. It was always something going on. Hackers mostly just trying out their skills. I got to the point that I kept my own weekly backups because the service provider was so bad. I finally dropped the site all together when all the members decided facebook was better.
When it happens again, and it will, just be patient and they will get it all back up. It might even take a day or two.
Hopefully a bunch of you know how to get a hold off each other offline. I know we are all good friends here!
