Problem with Sharing to Facebook

**UPDATE** 9/8/2014 12:00 PM EST: Over the weekend there have been reports of more problems opening shared links on Facebook iOS app. Here’s the scoop.

**UPDATE** 3/11/2011 10:00 AM EST: Facebook’s fix has been stable so we’ve reverted back to our normal sharing integration. We’ll continue to monitor Facebook sharing but everything is back to normal now.

**UPDATE** 3/10/2011 10:00 PM EST: Facebook has deployed a fix intended to address the core issue.  We are running a full suite of tests and will revert to our normal integration once this is confirmed fully functional.  We are currently still on an alternate integration, which works as expected with minor limitations on posts with multiple images.  We will update here once we resume fully normal operation.

**UPDATE** 3/10/2011 1:30 PM EST: Facebook has reenabled our workaround so we have been operating correctly for a few hours now.  We will continue to monitor in case of any changes.

**UPDATE** 3/10/2011 6 AM EST: Facebook has indicated a fix will be deployed on their side by “no later than Thursday evening”.  We are working with Facebook directly and will provide updates as they are available.  The mobile endpoint workaround will stay in place in the interim, so Facebook sharing is currently functional.  You can follow Facebook updates on this issue on their Live Status Page.

**UPDATE** 3/10/2011 12 AM EST: In an effort to keep the system as stable as possible while Facebook works on a fix for the root cause, we are currently leveraging Facebook’s mobile share endpoint for all shares. Though the user experience is geared to a smaller form factor, it does function correctly and allows us to continue to support sharing functionality.  Facebook has let us know that a fix will be deployed quickly; we will resume our normal operation as soon as that happens.

**UPDATE** 3/9/2011 6 PM EST: We deployed a workaround to restore core Facebook sharing functionality via AddThis while we await a more permanent solution from Facebook. We are continuing to monitor progress on the issue from their side and will keep you updated with additional information as we have it. In the interim, we believe the workaround re-enables all sharing features. Thanks for your patience.

This morning we got reports that their were problems with sharing to Facebook.  After some investigation,  it appears that overnight Facebook may have introduced a bug as part of an update that has broken Facebook Sharing.

With the bug, any url that hasn’t been previously cached within Facebook will initially not show the title and image of the page and then get an error when shared.

This bug has been discovered by a number of other developers and reported to Facebook.  We’re escalating the issue through our channels and hope to have it resolved as quickly as possible.

If you’d like to see the issue first hand or if you have a few extra special URLs, Facebook does make a tool that you can force URLS to be cached in their system.

We’ll keep you updated as things change.  Be sure to follow us on Twitter as well for the latest updates.
