I wish I could give you an exact time but i cannot. We have a new rack with better power supplies and batteries all setup. My server guy "Host" Will be moving our servers about 50 feet to the new rack. We estimate the downtime to be between 10-30 minutes only. again i cannot give you an exact time because no one knows that. This will just happen sometime tomorrow. This is being done to make this place more redundant. We cannot afford a UPS going out on us on this old rack. Thanks!
