Funny. I followed the "down=yes" link and got the "Service unavailable" page, as expected.
Then I clicked on the "down=no" link for fun, and the page partially loaded for me. I refreshed it and got the whole front page loaded. And then one more time and got the "Service unavailable" again...
After over 2 and a half hours of trying to get my order through, I was finally able to place my order. Confirmation e-mail just came in. I wish that the process would have been a lot nicer.
No automation, like others did. Just did a lot of clicking the "Process" button with a few breaks every so often. I would click on the "Cart" link every now and then, just to verify that my cart didn't get cleared out like it was earlier today.
