Tumblr broke the Gibson, apparently

staff:

A human error caused some sensitive server configuration information to be exposed this morning. Our technicians took immediate measures to protect from any issues that may come as a result.

We’re triple checking everything and bringing in outside auditors to confirm, but we have no reason to believe that anything was compromised. We’re certain that none of your personal information (passwords, etc.) was exposed, and your blog is backed up and safe as always. This was an embarrassing error, but something we were prepared for.

The fact that this occurred at all is still unacceptable, and we’ll be seriously evaluating and adjusting our processes to ensure an error like this can never happen again.

Please let us know if you have absolutely any questions.

If you’re a technical type, the nature of the data breach is explained over here. It doesn’t sound good.
