4-Layer PCB not eligible for DKRed

I have a simple dummy PCB (with the Raspberry Pi HAT design) made in Kicad with 4 layers. After I upload it to the PCB Builder, other manufacturers appear, but the DigiKey Red toggle is missing. The file is attached.

Can anyone tell me why this doesn’t seem valid for DKRed? I’ve used it for 2 layer boards of this shape before.

I am sorry, but DK Red is currently having technical issues and unable to accept orders. We are working on trying to correct the issue.

Alright, thanks for the information.

Does that extend to orders already made with DK Red? We put an order in for another PCB a few days ago and I haven’t heard anything about delays.

Hello, sorry, but yes. This is currently affecting orders placed last week as well. We are working to correct and also get an email out to everyone that is affected.
