Hello,
I m actually unable to order PCB on JLCPCB,
- Gerber file upload take a lot of time (at 91%)
- After trying to checkout, server return Error 500
I try with an other project I order since 3 days and this is the same behavior.
Can you tell me when online order will be available ?
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
All is ok now. My order is well done
