Probably mostly to do with laziness. Well, maybe somewhat, but the main reason is that my old site was hosted at OnlineFocus. There really wasn't a problem with leaving it there after I left the company and I was in no hurry to find a new host so I just left it as-is. However, sometime around mid-October OLFI "closed its doors". So I then had a site without a web host.
Because I was in the middle of a couple of other things I still wasn't in a hurry to find a host and I had some other plans for the site that caused me to wait.
But now it is once again live to the delight of my two or three regular visitors.
