This via blog post mentioned on the @Esri twitter stream… some changes are coming to the Online subscriptions as of Dec 31, 2010. This from the blog… ArcGIS Online services in Extended Support status will no longer be included in ArcGIS Online for-fee subscriptions on the premium servers (premium.arcgisonline.com) as of December 31, 1010. However, you will be able to access the older services for some time as no-cost standard ArcGIS Online services.
