Edit: I've just been doing a search of blogline feeds using their own search engine and I can't find anything more recent the 13th December 2004. This also appears to be affecting people all around the world.
Edit: Feeds are back! Hurrah. I've now exported them to a text file, just in case. It was nice to share a common cause with fellow bloggers who I've never met before, so there was some benefit to a couple of hours of inconvenience!
