Yesterday at 5 PM PST we released a fix for this issue. We confirmed with several top developers that they are not seeing further data loss.
Now that the immediate issue is resolved, we are working on a remediation plan in order to help developers restore lost data. We will provide more information in the next day or two once the plan is finalized.
We will also be posting a full incident report explaining how this occurred and what we are doing to prevent future incidents.
Thank you for your patience as we deal with this issue.
