X claims $100m annual savings upon exiting Sacramento data center

X, the social media company formerly known as Twitter, claims to have saved $100 million annually after exiting its Sacramento data center via a post on the platform. X further claimed to have saved a significant amount by repatriating some of its workloads to on-prem data centers.

The company revealed its plans to exit the Sacramento facility in December 2022, alongside plans to downsize the data center in Atlanta, Georgia, in June 2023. Its decision to leave the property required the moving and re-provisioning 5,200 racks and 148,000 servers.

"In total, we freed up 48 MW of capacity and tore down 60,000 lbs of network ladder rack before re-provisioning it to other data centers,” the company wrote on X. "This shift has reduced our monthly cloud costs by 60 percent. Among the changes we made was a shift of all media/blob artifacts out of the cloud, which reduced our overall cloud data storage size by 60 percent, and separately, we succeeded in reducing cloud data processing costs by 75 percent.”
