Possible Duplicate:
ajax.googleapis.com blocked by OpenDNS. Confirmation?

I'm not sure if this is the right place to ask this, but since this morning when I opened StackOverflow that error appears on the top of the page.

I'm on FF and I'm not using any popup/code blocker. I've tried also with Google Chrome but the errors remains.

Anyone else with the same error? How to solve this?

Thanks in advance

This sounds like a temporary outage (for you) of google's CDN. Check that you can download http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js . In particular, OpenDNS is known to block the google CDN.

It is also possible that a local proxy or other software is rewriting the page. Do allow us to determine whether that's the case, copy the source code (with Ctrl+U   Ctrl+A   Ctrl+C) of the root HTML page, upload it to http://pastebin.com, and post a link to it.

  • It returned to normal by itself :) Thanks

  • Yes OpenDNS seems to have problems with ajax.googleapis.com. I cleared DNS cache (ipconfig /flushdns) and re-registered dns (ipconfig /registerdns) and this removed the problem, only temporarily. It came back later and forced me to remove OpenDNS entries from DNS list.
