About 3-4 weeks ago I suddenly started seeing high latency on the e1000g
interface of my Ultra 27.
ping -s yahoo.com

I don't believe this is a problem with my ISP or home network since I have a
number of other
machines (laptop, Mac, PS3) that use the same network and do not exhibit this
behavior.
The routine table looks fine to me:

Around that same time I had an 'Update All' from the package manager but I'm
not convinced the two are related since I believe the high latency had shown up
first (which prompted the update).
Any clues would be much appreciated.
