On Wednesday 13 June 2012, an unknown error caused the removal of several zone files from the configuration of our reverse DNS provisioning system. Following up from the initial report published on RIPE Labs, we further analysed what caused the incident and implemented a number of procedures to decrease the likelihood of this happening in the future.
RIPE NCC members can browse RIPE database objects with history in RIPEstat for a couple of weeks as a demonstration. Please check it out and let us know what you think.
