I must apologise that the site was down over the weekend, and it took me a while to realise both that this had happened and that I'd lost material from last week as a result. I'm not sure why this happened, and will be looking into it. But fortunately, this blog is migrating in the next day or two to The Times's website (link will of course be provided when it's all ready) and I believe that all the posts, comments and archives to date have already been exported to the new site, so nothing will have been lost.
