Teraswitch has confirmed a loss of connectivity on our undersea cable between SEA1 and TYO1. This caused a very large impact to Tokyo traffic from global networks. At this time, connectivity is restored, and Teraswitch has diverted traffic away from using the affected cable until all vendors involved complete their investigation into the loss of link.
