After exploring several different options for servers at Rackspace Cloud and the requirements of Moodle 2.0 Woehler.us should be be up and running smoothly without any more interruptions. The new server is setup so that it can easily be load balanced should the need arise. The ram and hard drive space have also been upgraded to allow the system to run more smoothly. Thankfully I've been able to do this because the income from advertising has increased. It appears that Google analytics stats took a hit during the double migration between new servers. Hopefully that will return to normal levels soon.
