LinkedIn domain for sale?

Goodness. What's up with LinkedIn?



It's not like they forgot to re-register their domain - it's registered until 2018. Security problem at the domain registrar? Or maybe Qwest's DNS cache has been poisoned (or LinkedIn's own servers were temporarily taken over).

Qwest's DNS lookup says linkedin.com is 205.171.3.65, but LinkedIn's own nameserver at 156.154.64.23 says 216.52.242.86 (which reverse-resolves to careers.linkedin.com).
