Windows Vista x64 pulled from the MSDN site

I have been trying to download the x64 edition of Vista since yesterday and this evening it appears they have pulled it from the site.  Very strange!

My download terminated around 3 PM EST today and I haven’t been able to get it started again since, after I logged back into MSDN it has vanished.

UPDATE:: The Microsoft FTM seems to have started to download it again even though it still doesn’t display in the Operating System list.
