Hello Ian,

I=E2=80=99ve tried from a couple of networks as well as over Tor and I cann=
ot
reproduce it.  Does it still happen for you?  (Specifically I used =E2=80=
=98guix
download=E2=80=99 or =E2=80=98wget=E2=80=99 with the URL above.)

> Is there a way to specify the timeout in guix?

The =E2=80=98ftp-open=E2=80=99 procedure in (guix ftp-client) does allow yo=
u to specify
a timeout when opening the connection.  In (guix build download), which
is what is used when running =E2=80=9Cguix build perl-datetime=E2=80=9D, we=
 specify a
default timeout of 10 seconds.  This timeout cannot be changed from the
=E2=80=98guix=E2=80=99 command line though.

Thanks for your report,
Ludo=E2=80=99.
