Phase 2Phase UpdateUnderstanding sent to RSSAC for review.

 

Phase 2Board UnderstandingWe, the ICANN staff, understand the advice to be as follows: ICANN Staff understands RSSAC recommends the Root Management Partners increase: 1) the signature validity period for the root zone KSK to 21 days; and 2) the signature validity period for the root zone ZSK to 13 days. ICANN staff further understands that RSSAC does not consider this issue urgent, however it should be addressed within "a reasonable amount of time" (which ICANN staff will assume will mean within 6 months) to allow for process document updates and software testing.
