The server went down yesterday around 17.45 CET. At first I thought it was because of heavy DDoS attacks, but then the traffic report showed 0 bytes.
I contacted the hosting company, and they couldn't reach the server by ping, and it didn't respond to keyboard inputs, that was why I couldn't restart it through the control panel.
They had to make a manual restart to make it work again, but don't worry, no data was lost!
I am really sorry for the inconvenience, and I hope you will kindly overlook this.
Best regards,
Helga
