Some readers have been getting a generic (and gross) holding page rather than the usual Scary Go Round website today. From what I can work out, the domain name for one of my nameservers (the backup) lapsed so what you're seeing is some kind of spontaneously generated holding page. I don't think the DNS has been hacked, I haven't lost control of the site, or any of the other horrible things I thought might have happened this morning.
I have requested the necessary changes to fix this, so hopefully it will be sorted in the next couple of days. If you've not been able to see today's comic, have a look here.
