Southwest airlines website unavailable outside of the US for months

I live in the Netherlands, and have been trying to access the southwest airlines website for months. I've always failed at this, and the website simply blurts out:

Access Denied You don't have permission to access "http://www.southwest.com/" on this server. Reference #18.93643e17.1506590830.9a2c74

I've contacted customer support, and had this brief exchange:

"Well thank you for following up with us! Are you trying to access our website outside of the U.S. by chance? ^Emilia

Yes, i am in the Netherlands. Why would that make any difference?

In the meantime, we'd be happy to help you phone at 1-800-435-9792.
