Apple announced that its iWork.com service will be discontinued on July 31, 2012. It's not surprising as the company's iCloud service has the same features.
"After July 31, 2012, you can no longer publish new documents to iWork.com from any iWork application on your Mac or iOS device. Documents already shared on iWork.com will not be available to you or to those you shared documents with.
Moving forward, you can use iCloud to share documents between your computer and your iPhone, iPad, or iPod touch. Learn more about or sign up for iCloud."
