[Apologies for duplicates] Dear Colleagues, As outlined by Joe Abley, ICANN, on the RIPE DNS Working Group mailing list, the DNS root servers will switch to a signed .ARPA zone at the beginning of next week. The mailing list archives can be found at: http://www.ripe.net/ripe/maillists/archives/dns-wg/index.html As the operator of K-root, the RIPE NCC has planned a maintenance window on 15 March 2010 between 09:00-13:00 UTC. During this period we will roll out the signed .ARPA zone. We will inform the working group once this change has been carried out. Regards, Wolfgang Nagele RIPE NCC DNS System Engineer
