Hi All, Tomorrow Saturday June 3 at 12:00am EST, we will be taking down one of the round robin www servers for the IETF (209.173.53.180) for 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 no be affected. If after 01:00AM 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@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
