Why is the NSF blocking the Wayback Machine?

Susan Nevelow has discovered that the National Science Foundation (NSF) blocks the Wayback Machine from copying its web pages, and would like to know why.

PS: Good question. I'd like to know too. The web pages we're talking about are already OA at the NSF site.

Update. Bill Hooker at Open Reading Frame wrote to the NSF webmaster and got a direct answer:

NSF blocks all indexing of the site between 7AM and 7PM ET, our peak traffic hours, for the convenience of our users. However, there is no block on the site from 7PM to 7AM ET. This is standard policy for most high traffic sites. The owner of [the Wayback Machine] need only comply with our policy in order to index our pages.
(Thanks, Bill.)
