Update 2019-05-09 09:00

We are at the final stages of the Bianca maintenance.

Update 2019-05-08 17:00

Bianca requires more service and will most likely be returned to production tomorrow. As Bianca is a SNIC-SENS system there are additional layers of security that needs to be serviced, hence why we often one day of maintenance work is not enough.

Maintenance completed for Rackham, Irma and Snowy. Service for Bianca continues. Next update at 17:00.
