I just happened to take a look at the output of a Web log analyzer and noticed a huge increase in traffic yesterday. I thought that was odd, since I hadn't written any new blog posts recently or published new stuff on my Web page. So I took a look at the logs themselves and noticed that a whole bunch of my recent hits listed their referer as planet.debian.net. This is where you start getting a sinking feeling...and yes, when I checked the Planet in a Web browser, sure enough, it looks like my whole blog got dumped out on the Planet. For some reason my own RSS reader didn't pick it up, so I wouldn't even have noticed if I hadn't been checking on my Web server stats.
I'm not sure why, but I bet it has to do with the fact that I upgraded ikiwiki yesterday. So if you've seen the new ikiwiki version that came out recently, take a little care when you update and make sure it doesn't impact your RSS feed.
