The maintenance session will begin on 17 November morning and it is expected to be completed by 19 November but may extend into November 20.

Hi,

I do not know if this is related to the above mentioned maintenance, but data for the 16 November stays unavailable via both the GUI and the API.

Thank you

Thanks for pointing this out. I’ll contact the data providers to get this fixed.

Luke.
