Vaughan,
Lee is working with Current.net - and others are working with/through their ISPs to get this resolved. Sorry I couldn't email you sooner - my personal website connects to my school email and outbound email is filtered - I don't think it would believe I have any parents that live in Australia & send students to the US
Still no official word, although I know 4.78.216.2 is either the problem or the node right before the problem. Hopefully a fix is right around the corner.
Bryan
