All - A number of IETF services were impacted by an unexpected outage. The impacted services included the Author-tools site, Notes, the new Wikis, staff email, ticketing and Zulip. The cause of the outage was a malfunctioning backup job on the cloud platform which caused a physical host to exhaust logical disk space. This in turn caused the cloud virtual machines to experience degraded service. The problem has been identified and corrected, and all services are now back online. I apologize for the inconvenience.
