Well I’ve done it!
I’ve rebuilt my main linux box… it’s now a XEN server, and the webserver is now running in it’s own virtual domain. This will prevent me from breaking things when I perform updates (in theory anyway!).
For the last 26 days this site has been running from a virtual machine on my Windows 2003 server. I’ve had all sorts of problems during this time, slow responses, time drift issues, etc.
