Like Ricardo, I get the correct hash everywhere:

--8<---------------cut here---------------start------------->8---
$ wget -qO - http://berlin.guix.gnu.org/32hy1jqkam201l7c4wg3bhxz4x5l5jy0.na=

Could you run these commands locally and see what you get?

Could it be lack of disk space or a transient networking issue on your side?
