This schedule is updated daily to indicate progress. When each server is upgraded, it is offline for less than ten minutes, usually less than five, during which the critical software changes are made. The server then boots under the new operating system and resumes operation. At no time is user data affected by the upgrade. This upgrade brings some important changes to functionality, including a few that can affect how the server works for you.

We have been looking forward to this upgrade for a very long time. Through a global array of Web servers and caches, pair Networks will bring your Web site content closer to visitors, increasing performance and uptime for your site. Even with the excellent diverse connectivity we have in our Pittsburgh datacenter, the speed of light limits how quickly a Web site can respond to a visitor - a limit which becomes noticeable for visitors from distant corners of the globe. Also, there will always be some networks which we can reach only through crowded peering points or suboptimal routes. By delivering Web site content from caches on various networks in other cities, we can eliminate the obstacles presented by geography and peering points.
