Just after I wrote and saved a long article yesterday, the computer with this website crashed.
I couldn't reach it at all, so that meant that either my parents' internet connection went down, or the computer itself crashed.
My father went to check on the server, and found out that the CPU fan was broken. The main board had detected that, and shut down the computer to prevent damage to the CPU. Jaap immediately installed a new fan so when I woke up it was up and running again.
Thanks a lot paps!
