Dear colleagues, On Thursday 16 March 2017, a bug in a script caused an outage for some reverse DNS delegations registered in the RIPE Database. The effects of the bug were not immediate, but began a cascading failure, that persisted until Friday 17 March. In this RIPE Labs article, you will find more information about what happened: https://labs.ripe.net/Members/anandb/reverse-dns-outage-for-out-of-region-ad... Kind regards, Mirjam Kuhne RIPE NCC
