Additional Windows Live Messenger PIC/Federation IP Address - Postponed

Tomorrow’s planned added capacity has been postponed for technical reasons and to provide additional time for administrators to update their firewall settings if necessary to reflect the additional IP address. The new date that this work is scheduled to go into place is Friday, March 26, 2010. For organizations that have chosen to restrict this traffic to specific IP addresses, you must have the list in KB897567 in place prior to Friday, March 26, 2010 or PIC connectivity with MSN will fail.
