I have to admit that I'm a little puzzled whenever this happens on a well-known site. Do not all registrars allow you to set up auto-renew on your domains? I have to explicitly choose not to renew a domain.
They probably bought a long registration and the card they used expired during that period.
The latest I've heard is that it wasn't due to expire for another year, but Network Solutions decided it was expiring anyway.
I'm confused - this simply appears to be the usual Haskell landing page. What is it that's happening that you're claiming to be "odd" ?
The domain was expiring and got redirected to a Network Solutions domain parking page. It looks like it's been renewed, but the correct dns settings don't seem to have propagated everywhere yet.
