You are about to download the full-sky HDF for the Gaia DR2-derived astrophysical parameters. Note that this does not (as of 2021) work with astropy. You will fairly certainly need VAEX to do something sensible with this data.
This is about 90 GiB On a line with a constant throughput of 10 Mbit/s, downloading this will take about one 1 day.
If your download is interrupted after transferring sufficiently many Gigabytes, let us know and we'll try to assist you in resuming it.
