I didn't install any firewall (this was within a safe network). "ip
route ls" gave something like

xxx.xx.36.0/22 dev eth0 scope link
169.254.0.0/16 dev eth0 scope link
127.0.0.0/8 dev lo scope link
default via xxx.xx.36.253 dev eth0

this checked out with another linux (located in another building) box
that is working.
I cannot ping the gateway itself. if I type
traceroute IP-of-gateway
1 hostname(xxx.xx.36.33) 2999ms !H 2999ms !H 2999ms !H

Every diagnostics looks fine - yet it is dead - I am totally clueless.
The LEDs on the back of NIC are fine (I see both green and blinking
amber). If I unplug, mii-tool gives me "link down". Did the networking
people give me wrong sets of IP/gateway for this location?
