I know almost nothing about the servers configuration, so I'm experiencing some problems with my new VPS.
1. Often homepage switches from normal working regime to this index: https://lh4.googleusercontent.com/-J.../s901/down.png
2. When the first problem is active, also it's not possible to make connection to server via remote control applications such as Putty, WinSCP;
Could this be an Apache2 configuration problem?
Temporary the problem disappears after restarting server.
Ubuntu version: 12. 04
