This incident has been resolved. Have a great weekend and happy schema checking!

We have implemented a fix that should allow the "mark as safe" feature of schema checks to return to full functionality. No data was lost during this period, though incorrect results were displayed as to whether operations were previously marked as safe or not. We apologize for the confusion during this incident and thank you for your patience.

At the moment, the "Mark changes as safe" feature in the Checks page is currently broken. On a failing operations check the button on the check details page will say "Changes marked as safe" even if it has not has been marked as safe.
