comment 100% uptime for a web application
-1 because this is a practical answer but not useful at all. All questions in this site could be answered by "hire someone else to do it", but that is not why we are here.

comment How do I switch servers for a web site with minimum disruption?
No, but you should test the new public IP first to make sure it's setup correctly and your website is reachable, before switch the DNS entry.

comment Debian squeeze high memory usage?
Disk buffer caching is very important for performance so it's healthy to leave lots of RAM for this purpose. Just keep this in mind.

comment Intermittent MySQL database connection errors on Ubuntu server
You should try leaving vmstat 5 running all the time, until the problem happens again. Also have a separate screen running: iostat -x 5. Then when your system hangs, copy the last 10 values of the output of those guys and look for suspicious things. But remember we can't troubleshoot everything for you, that's not the purpose of this website.

comment Intermittent MySQL database connection errors on Ubuntu server
At the time you ran vmstat your system was pretty quiet. The only fun stuff that happened were a few blocks of data being written into disk. But that's low volume.
