Dear Matt,

Thank you for contacting Online Support.

Go Daddy is the world’s largest domain name registrar with more than 50 million domain names in our portfolio. Go Daddy has a full time presence in Washington D.C. and takes an active role in Congressional and legislative proposals.

Included in Go Daddy’s legislative efforts is the Stop Online Piracy Act (SOPA). We are currently reviewing the most recent legislative proposal and continue to educate ourselves on the many facets of SOPA. We look forward to working with Congress to refine legislative language about this issue when appropriate.

To review Go Daddy's statement on the matter, you can read this article:

If you're getting this error trying to use ApacheBench on OS X Lion:

Benchmarking mwmanning.com (be patient)...apr_socket_recv: Connection reset by peer (54)

You need to download the latest beta version of Apache and rebuild ab. Here's how (assuming you have homebrew installed).

brew install pcre
tar xzvf httpd-2.3.15-beta.tar.gz
cd httpd-2.3.15-beta
./configure
