Dear colleagues, This is a follow-up to our message of Friday about issues with some reverse delegations. After doing a thorough analysis, and with the help of ARIN staff, we found more issues with our zonelet generation code, and this showed that we had indeed published some empty zonelet files. From ARIN's point of view these were valid zonelets, with no content, and that is why the delegations were removed. Similarly, three zonelets that APNIC picks up also had empty content. We fixed these issues late on Friday afternoon, and by Friday evening, both registries had re-imported the correct zonelets and were again publishing the missing delegations. We will evaluate our code review and testing to prevent this from happening again, and add some monitoring to alert us to such a situation earlier. We are also discussing this with the other RIRs to find ways to improve the zonelet exchange process.
