According to the Dallas Morning News, the team forgot to renew the dallascowboys.com domain, and the site was left blank. The Cowboys' marketing arm, led by one Jerry Jones, Jr., quickly renewed the domain, but that process can take up to two days to go through, and for a website to propagate on a domain -- even if it's been there before. The site is up, but until Tuesday morning, there were people on Twitter reporting that they could still see the "fail" page on certain browsers.
