ICANN Postpones KSK Rollover

Posted: Friday, 29 September 2017

On 27 September, ICANN announced it has postponed the change to the cryptographic key that helps protect the Domain Name System (DNS). This change, more commonly referred to as the KSK Rollover, had been scheduled for 11 October, but recently obtained data revealed that a significant number of resolvers used by Internet Service Providers (ISPs) and Network Operators have not been updated in preparation for this change. Because of its critical nature, it was determined that it is prudent to postpone rather than risk adverse effects on global Internet operations.

Please refer to ICANN’s announcement for additional details:
