On the 3rd of March, for the first time, I experienced what it meant if a server stops responding.
Because mine went down for around 12 Hours before I was able to fix it.
The cause was a corrupted GRUB2 Bootloader. And after an unscheduled restart. It wasn’t able to get back up again.
In the end I used a KVM device to remote into my machine. It exposed the problem and we fixed it.
Quad, a good friend and Mentor of mine, was of really good help. Thanks again buddy.
