Dear IETF Community - As you know, we recently completed an upgrade to a new OS, and we have been in the process of updating software and dealing with configuration changes since then. Today, we had a short failure with Mailman. A number of emails sent to IETF lists between the hours of 11:30 and 13:00 Pacific time, (1930-2100 GMT) did not get processed properly by Mailman. If you sent a message to a list, and did not see it delivered, we ask that you please resend that message at this time. We apologize for the inconvenience. Glen Glen Barney IT Director AMS (IETF Secretariat)
