The Feds are about to pull the plug Monday on their DNS server
workaround that has been foiling the DNS-changer virus.  It's thought
that there are still 60k or so machines infected in the US which will
lose internet connectivity on Monday if not cleaned, so it might not
hurt to check and make sure you're not one of them.  Snopes.com has
the dope including a valid checker address:
