Same with me, cannot get to this site anymore,
http://www.jgiesen.de/daylight/Its a nice chart for daylight for any city in the world you want.
Many other fun things, but it wont work any more.
Ive installed the newest Java and gone thru all the troubleshooting for each browser on my computers,,,,,,,nothing.
Get the same error message on them all.
Even tho I have the site unblocked, it is still blocked. Tho other sites that use Java are OK.
Oh, well, I will just have to go outdoors and look at the sun angle,,,,,,,
