Now I am not able to ping update4.freebsd.org and update1 so I fixed
the address to update2 and the first part works now it stops at:

...
Applying patches... done
Fetching 4716 files... failed.

I am in Europe if that helps the people who maintain the servers. How
do I go about reporting this to them??
TIA
