Maximum dimensions

What is the maximum PCBA board size?

Using the "Instant quote" form I get a warning:

"The PCB size exceeds the maximum size 570x470mm for PCB assembly."

But looking at the "Capabilities" page for PCBA it lists a smaller maximum dimension:

"Dimension, Single PCB Size: 10x10mm - 470x500mm"

So that is the maximum PCBA size? Thanks!
