Well congratulations, Melbourne International Jazz Festival... If you go to http://www.melbournejazz.com this evening, this is what you get: The server is temporarily unable to service your request due to the site owner reaching his/her bandwidth limit. Please try again later.
The 509 error on a website 'Bandwidth Limit Exceeded' often means that a website's getting more traffic than they allowed for.
Maybe it's the links in this blog, which as we know is very very popular reading... every time I link to Melbourne Jazz they get thousands of visitors! Sorry, guys!
