As probably mentioned, my website was unreachable the last 2 Days. The reason for that was a filesystem crash of the server at server4you.de where my vserver was hosted on. Cause of that outage, I decided to switch my email and websites to a new hoster.
Now my website is hosted on the high-available cluster of www.packagecloud.com. They provide a high available environment with everything you need for webhosting for just 5€ per month. Very nice offer, have a look. 🙂
