On September 20, 2026, Amazon disclosed a commitment of nearly $400 million to public water infrastructure in Eastern Oregon. This is regional infrastructure support, not a financing allocation to an individual AWS campus or confirmation of completed construction. AWS's US West (Oregon) region is supported by a broad, still-growing network of data center campuses in Morrow and Umatilla counties. AWS US West (Oregon) Eastern Oregon Program is in Boardman, Hermiston and Umatilla area, OR, US and is a program with partially operational status.
