Unable to Download utility_mapping Full Database

I was unable to download the data using the following command:
humann_databases --download utility_mapping full .

The output was:

Creating subdirectory to install database: /mnt/utility_mapping  
Download URL: http://huttenhower.sph.harvard.edu/humann_data/full_mapping_v201901b.tar.gz  
CRITICAL ERROR: Unable to download and extract from URL: http://huttenhower.sph.harvard.edu/humann_data/full_mapping_v201901b.tar.gz  

It seems that the server might be down, as I am also unable to access the website: https://huttenhower.sph.harvard.edu/

Indeed, there was a long maintenance window for our systems last week. Everything should be back up now?

Yes, I’ve already downloaded the database. Thanks.
