Visited other sites on the server, they were OK. Hit reload in Chrome, and still got the error. Visited update.php and then the administration pages and back to the home page and all was well again.
So either something really weird was going on and going to update.php or admin jogged it back to functioning, or more likely it was a temporary error and Chrome cached it.
Update: This was probably due to server overload, probably stemming from http://data.agaric.com/raw/anonymous-comments-dos-attack
