The scheduled outage of the IETF email processing system has been deferred again to allow time to complete further work discovered to be required for a successful transition. This transition is being undertaken by Sirius, the company selected to migrate the IETF’s email processing systems to a new cloud infrastructure and manage our email and mailing list systems. If the transition can not be completed on 29 August we will revert to the current infrastructure and reschedule the transition.
