It's coming back online soon, Insha'Allah:

The new hosting info:

Name: anwar-alawlaki.com
Address: 72.47.224.162
Host and network access provider: Media Temple, Inc., 8520 National Blvd., Building A, Culver City, CA 90232 USA, +1-877-578-4000, abuse@mediatemple.net

Media Temple is currently providing name service to Sheikh Anwar, and his domain is registered through DomainsByProxy, Inc., of Scottsdale, AZ.

Meanwhile, I have a pretty good archive of the dear Sheikh's site, circa October 2009.

You'll have to email me for access to it, and if I don't know you, be prepared with a plausible explanation as to why you should have access.
