I am super happy too!
I am also happy that the problem was not a big one, as nothing was broken. From what I could understand, I had some backup files that were left on the server and when I did the last backup, it was backing up the backups too, meaning it was creating HUGE files and using an insane amount of resources, and that is what got all the sites to not be able to load. Now, those files are removed and the resources are released back to let the sites load.
Thanks for your patience. I know you were not the only one wondering about it!
