Due to insane demand to sign up for the Old Spice Experience Challenge to raise your Xbox 360 Gamerscore by 1500 points, Microsoft has extended the promotion for another 3 days till April 15th. The website is still currently down to register, but should be up in 48 hours.

The original story and prizes you can earn are here.

Thank you for the incredible response to Xbox Rewards. The gaming community’s interest has temporarily overloaded our servers and caused delays for those trying to register.

To help ensure everyone who wants to participate has the opportunity, the Old Spice Experience Challenge will be extended by three days. Now you have until April 15th 2007 to increase your Gamerscore by 1,500.

As a bonus, we are adding more rewards for this challenge, which means more gamers who successfully complete the challenge will get rewarded.

Our development team is hard at work to fix the problem. We expect the web site will be ready in 48 hours, please be patient and check back periodically.
