Is it all uploads, or only for the wizard? You could try the old upload form (I think it's still active?). Also, you could try to upload to a local wiki. 

Testing different (local) ISP's might indeed also be a good one.

1) At some hours of the day the uploading works just fine, at some hours
it doesn't (and we can't figure out regularities in the hour patterns).
The tests are done using the same ISP, OS, and browser for consistency.

 Is interface language always the same too?


2) On Chrome from iOS users see this error: http://imgur.com/48kwWn2

 What step of the upload wizard is this? Is it expected that the "id" parameter uses non-arab numbers?

Debugging the network is probably useful. MTR is the standard way; if the user really only has iOS, available software looks very ugly, but something like https://itunes.apple.com/us/app/inettools-network-diagnose/id561659975 might be ok.


3) When the user uses VPN, it works (but uploading with VPN is slow and
they prefer not to do it.)

 I assume the VPN goes through another ISP?
