I am pleased to report that one of our production servers has been running non-stop since the first time we turned it on, with an uptime of 557 1/2 days!
Back on March 5, 2008, we fired up our newest server at the time to serve mysql for the smalldog.com website. As I recall, it took about 2-3 hours to enable mysql and transfer the databases over.
As of today, the server has been up ever since.
Thanks, Apple, for making something that just works!
