ICANN has scheduled the Root Zone Key Signing Key (KSK) Rollover for today, and it could affect some DNS users all over the world.
By Rolling the KSK, ICANN implies that a new cryptographic public and private key pair will be generated and the private key will be distributed to internet service providers, enterprise network administrators, and Domain Name System (DNS) resolver operators.
KSK Rollover operations began in October 2016 and were scheduled for October 2017. However, ICANN announced that the rollover has been postponed due to the fact that “a significant number of resolvers used by Internet Service Providers (ISPs) and Network Operators are not yet ready for the Key Rollover.”
A draft plan was announced on February 1, 2018, after receiving input from the community; October 11, 2018, was the date put forward to initiate the procedure. According to ICANN, the rollover is necessary to curb the rising number of cyber attacks.
