Well, that was unfun... my server was down for several days. As you can see, it's back now, but it was not an enjoyable experience having my online presence evaporate. Unlucky server issues were compounded by less-than-forethoughtful decisions on my part, which extended the outage beyond what it should have been. Lessons learned.
Much thanks to my server hosting company, Peak Web Hosting for their support (even on 5am Saturday morning!). You guys rock.
To everyone trying to download my Lightroom goodies, my apologies.
