Root Zone Trust Anchors updated

[Kim Davies]

Yesterday, we successfully completed Root Zone KSK Ceremony 28. Part of this ceremony was to replicate a newly generated KSK in our key management facility on the US West Coast following its creation at the prior ceremony on the US East Coast in October 2016.

Now that the KSK is safely instantiated in both locations, we consider this KSK operational, and the Root Zone Trust Anchors file has been updated to reflect this. The KSK generated in 2010 is still being used today but it is planned to transition to the new key later this year. Software implementers should make sure they have up-to-date root zone trust anchors and/or update mechanisms such that either trust anchor can be used to verify the root zone KSK.
