What is the best global time for uploading CNC observations?

Hi all,
I wonder what is the best time for uploading pictures in CNC days to help servers? There surely will be high impact on iNaturalist hardware. So, at what time the servers are the most empty? I guess there could be two or three peaks of heavy upload (corresponding to evening time in Australia/E Asia, Europe/Africa, and across America), but is it possible to see some graphs? This might be helpful to plan schedule after CNC.


Based on last year, just do it on your schedule. There will be no slower period.
