 Ah........ in which case traceroute did not work for me either at least 
the host was unreachable.
Which means that www.bom.gov.au  does have ICMP blocked.  As does my 
provider.

Results of nmap show my provider has almost every port closed including 
the usefull ones
and now they have blocked ICMP as well.

I rather think other advice about finding a new ISP is probably the 
easier option.
Rather  than waste time trying to trouble shoot  this one.
Or would be if I did'nt live out of Albany.

I was hooked on checking the weather every day.  I guess this means I'll 
just have to go
outside and check it myself.

Thanks for the comments and advice.  As always on this list I have 
learned plenty even
if I have not solved my specific problem. Or at least not in a way I was 
expecting.

Thanks all.

Mark
