We've created an updates resource center Web site that features articles about software updates for a SharePoint Foundation 2010 or a SharePoint Server 2010 environment.

In addition to posting the lastest information about cumulative updates and service packs, the updates resource center links to up-to-date articles about the nature of software updates and our recommended approaches for mitigating downtime when you install an update on farm servers.

All these approaches are based on the software update deployment cycle, which is shown in the following illustration.

Visit the Updates for SharePoint 2010 Products site to learn more about the software update deployment cycle and explore other relevant topics.
