Hi All, Unfortunately due to a hardware problem we need to schedule another maintenance outage of one of the www.ietf.org web servers. Today Sunday June 4 at 09:30pm EST, we will be taking down 209.173.53.180 for more maintenance in preparation for supporting IPV6. The outage should be less than 1 hour. This system also serves as the primary site for... noc.ietf.org www.iab.org www.iesg.org so those sites will also be down. Mail and the mailing lists (and their archives) should not be affected. If after 10:30PM EST you experience any difficulties, or notice anything amiss with the sites, please send email to ietf-action at ietf.org, the IAD at iad at ietf.org, and copy ietf-admin at techsquare.com and rpelletier at isoc.org. In case of an emergency, please call the emergency number: +1 301-858-6268. Thank you for your patience. IETF Secretariat. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
