Note on Facebook’s Application Stats Reporting Bug

As many developers may have noticed over the past couple weeks, starting around the beginning of the month, Facebook began reporting some suspect traffic numbers for certain applications. For example, some applications have seen steep increases in reported traffic numbers that do not match stats that developers themselves are seeing in their own logs.

We’ve been in detailed conversation with Facebook about the issue, which they confirmed was a bug when it first appeared two weeks ago. Facebook says they are still working on correcting the bug, though they don’t know exactly when numbers for the affected apps will be corrected.

In the meantime, we’ve taken the step of flagging applications on AppData that have clearly had suspect gains reported by Facebook. For those apps which we’ve flagged, we are instead using the last accurate numbers from before the bug appeared in calculating developer totals. We’ll let you know as Facebook resolves the issue.
