Resolved after 3 hours 13 minutes, affecting Inbound Voice, on January 17, 2019.
The service has remained stable since the last update. We have received an initial RFO from the upstream operator concerned, who have advised that they suffered a major DNS failure on their primary and secondary systems from approximately 09:00 to 09:18 this morning - however it is unclear at this time whether this outage caused the issues we saw around the same period earlier. We will provide a full RFO ourselves shortly as soon as we have further information available.
