Oh, dear - I didn't even notice the original message said that the threat was being caused by the FBI.  Apologies - it's been a crazy day, and I do completely know that this is something the FBI STOPPED but that could cause internet connectivity loss if you have one of the affected DNS servers listed on your computer.  Which is why I put up the link to the FBI's site where they explain the whole thing.

Cheers,
Alisa
