Our network gateway has been restarted by the on-site team. We did run into some issues when the site came back online due to the volume of traffic being generated through the content federation and federation updates, we've scaled back some of the content processing for the time being to try to keep the site running stable.
We have agreed with the hardware vendor to return this model of hardware and will be ordering and replacing it with a more powerful version which we hope will operate with greater stability.
