Error locating server...(has that site been pulled?)
I had trouble accessing it when I first went to find it and I thought it was defunct.
I kept trying and Google asked if I wanted to see their cache copy of it...
http://webcache.googleusercontent.com/search?q=cache:http://stdcarriers.com/registry/search.aspx
After that I was able to access the site.
Not sure why but access seems sporadic.
At the moment I’m having difficulty pulling it up.
