The jquery.com site is up and running again. The DNS is still propagating across the net, so it might not be available quite yet from every location, but it should be fully reachable within the next day.
I'll leave source files on my server for the next couple days, so feel free to grab them from here (see previous post for details) if you're still not able to get to jquery.com.
Thanks, everyone, for your patience.
Also, if you'd like to donate a few bucks to help John with the setup costs for the new web host, you can do that here or on the jquery.com home page:
