There's too much to unravel here.
You must spilt the heirarchy:-
1. your network
2. ETHO: are you trying something new/untested
3. ETH seems to be sleeping/broken
4. Switzerland seems broken: definitely the local embassy;
   and AHV is trying to screw me.

For confirming ETH's servers, I often use somethink like this 
logger:  `<theLogger>   <File of ListofURLs> <File results to>`

#!/bin/bash
echo ' get headers to $2'

for url in `cat "$1"`; do 
  echo $url >> "$2";
  echo >> "$2";  #  bare echo == newline
  curl -I "$url" >> "$2"; 
  echo "<><><><><>" >> "$2"; done
----------- end of script to fetch headers.

This fetched the URLs listed in <arg1> which were:--
http://www.oberon.ethz.ch/
http://carnot.yi.org/NetworkExtant.jpg
ftp://ftp.inf.ethz.ch/pub/ETHOberon/license.txt
ftp://ftp.inf.ethz.ch/pub/ETHOberon/Unix/release.txt

ftp://ftp.inf.ethz.ch/pub/ETHOberon/Native/LinuxBased/
ftp://ftp.inf.ethz.ch/pub/ETHOberon/Unix/x86.Linux/

And listed what the <headers> were in <arg2> which gave me:-

So the first 2 entries, including your URL, seem ok.
If I had time, I'd first check from my records, that 
curl -I <ftp URL> is valid syntax, like it is for http.

`curl <get the header>` is usefull to confirm the file-size
before d/l-ing some suspected monster-File.

BTW such fetches operate in background while you are
fetching your email etc.
