Every time I went to update my blog in the last couple of weeks, the site was down. Upon investigation, it turned out that the site wasn’t actually down — my IP address had been blocked. So, when I was home, it appeared to be down — when I was traveling, it didn’t. I had observed that the site appeared to be unstable — but I was traveling a lot — and didn’t correlate the apparent “outages” with being home. Last couple of weeks, I wasn’t traveling — so the site was “down” all the time.

It’s fixed now.
