Wasn't Facebook's domain, or at least their whois record, hacked via MarkMonitor in February? At least that was the initial report; I'm not sure what happened and it's hard to find a credible source about it. Here's the best I found in a short search:
Of course if it was hacked it wasn't necessarily MarkMonitor's fault; it could be Facebook's (though good security would anticipate that some customers will have poor security).
(If that post looks familiar, yes I'm reposting from a few days ago when someone made a similar comment. I'm hoping someone knows more about it.)
