I think so as well. Oddly enough that post on TC rose to the front page of reddit at the same time HN was down.

It's been sitting on the front page for the past few hours. I suspect several sources led to the TC article and then through to the post on HN.

This was also submitted earlier today to /r/technology:

Unlikely, TC typically delivers <10,000 mentions to your site if the article is about your site. For a mention I doubt it generates significant traffic.

That would be my guess as well. Although I am really pleased Codecademy has Python now.
