The Geography Network, which made its debut at the International ESRI User Conference back in 2000, is being shown the door by ESRI. The ArcGIS Online Blog made the announcement today.
With lots of changes over time to online GIS and geographic information and the technologies used to serve them, the Geography Network has been replaced by better alternatives to publish and find data (like ArcGIS Online). Much of the same exact content, and much more content that has been updated, can now be found and used in easier and better ways. So ESRI is planning to retire the Geography Network in late December 2009.
The online data portal is being replaced by ArcGIS Online where users can find and share maps, layers, and tools.
