Not sure how general this observation is, but I can confirm that *.sourceforge.net is inaccessible (telnet, or ping) from my expressvpn servers. Disconnecting the vpn makes them available again.
Note that all the 3.6 url's are blocked in this way.
Once i disconnected the vpn temporarily, the fonts installed as expected.
Bottom line: sourceforge is unreliable. files need to be located elsewhere.
