If you code a URL and use Automatic URL parsing, you need to put spaces before and after the URL. The comma after your link was taken as part of the link. I moved it outside the [****/url] tag for you.
If you’re using a library’s computer, someone more than likely hacked the proxy server to either forward you to another place when you go to Google, or display a cache page that they placed in there. Best thing to do is report it to a librarian so they can tell the system administrator.
Google has several datacenters (servers), so it’s possible somebody hacked one, - the others would be normal. But I’m doubtful Google is hacked (no mention of it on the webmaster boards), so it’s probably a proxy or a router.
