There seems to have been an awful lot of downtime here at EU lately (including most of today!). I am monitoring this and will move hosts if I have to to combat this should it recur. My hosts assure me, for the 3rd or 4th time, that they've found the source of the problem and corrected it (this time it was too much server load). Hopefully normal service will now have resumed, but I'll keep an eye on it. In the mean time I'm sorry for the hassle.

Update: I've moved the site to a new host. If you're reading this your ISP's DNS records have already updated, i.e. your ISP knows the site has moved (unfortunately as of an hour ago my own hadn't). The rest of the interwebs should catch up over the next 48 hours or so and normal service will then resume.
