In the world of computers, it is never a good situation to have a single point of failure, or a single copy of data. Having three of something—often referred to as "N+2 redundancy"—especially in different geographic locations, is considered ideal for truly redundant and highly reliable systems. However, the Bible talks a lot about the "four corners of the world" and it has long been our desire to reach those four corners, both figuratively and physically, with the preaching of the Gospel. By establishing a Vault Network across four geographic locations worldwide, we will achieve the strongest fault tolerance by maintaining multiple full copies of the entire sermon library with distributed load. It is the ultimate protection measure that will ensure the long survival of this treasure far into the future. **The Vault Site:** https://www.sermonaudio.com/vault
