Arpresolve cant allocate; ISP production Server DOWN!

[Lewis Watson]

Please help me figure out what's happening here. I have a www server in
production that is getting the following error "arpresolve: can't allocate
llinfo for 65.202.119.1" (my gateway). All network connectvity seems down
but ifconfig shows up with all local ip addresses are pingable. anything
off this machine is not pingable. Please help. I rebooted even but nothing
has changed. Any ideas?
Thanks!
Lewis
