I'm now able to do a dns lookup of gcc.gnu.org (it was failing for a
    short period of time after the move):

The system moved physically.  The firewall at the new location
blocks traceroute.  You'll see this with the other hosts there
as well such as vger.kernel.org.

Traceroute icmp is blocked at the last hop you see. This is fairly common 
practice and does not indicate anything in regard to the reachability of
the host. When traceroute works, the only thing that it indicates it the
path across the internet at that _exact_ point in time that you had from 
point A to point B. Traceroutes can also change right out from under you.

But the only reason I tried traceroute is beacuse I couldn't get to
    gcc.gnu.org any way at all; w3m, ftp, wget, all fail.

The system has not been up reliably.  It has been crashing such that
it responds to ping but not to anything else.  Matthew has been
investigating.

It is up at the moment.
