It seems the Java download site has been down for 24 hours. Many internet posts by folk receiving “This page can’t be displayed” after clicking the download button. The “See all Java downloads” page results in the same message.
A site test reveals it is down as well: http://downforeveryoneorjustme.com/javadl.sun.com
I did find the Oracle site worked without any problems: http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html
