Missing geopotential data at 1.40625deg

Hi,

I was downloading data from Weatherbench and noticed that the geopotential data at 1.40625 degree is currently missing https://dataserv.ub.tum.de/index.php/s/m1524895?path=%2F1.40625deg%2Fgeopotential. When will it be available on the data server again? Thank you.
