As many of you use the IETF WebEx account for IETF virtual meetings, we thought it important to let you know that tonight, Friday May 12, 2017 between 7:00 PM and 11:59 PM PDT (GMT-7), Cisco will be applying an Emergency Patch to the WebEx Meeting Center. Please note that after the patch has been applied to ietf.webex.com, you will receive the new version of the WebEx meeting client upon entering a session for the first time. IETF Secretariat
