This was our first significant outage of the network. This post describes the incident, how it was addressed, and what we are doing to prevent future incidents and improve our responses. * [Sovrin Status Twitter](https://twitter.com/sovrin_status) ## Sovrin Stewards The Sovrin ledger is operated by Stewards, trusted organizations within the ecosystem who have agreed to abide by the requirements in the [Sovrin Trust Framework](https://sovrin.org/library/sovrin-governance-framework/) and are responsible for operation the nodes that maintain the Sovrin distributed ledger. Stewards also, as a group, accept or reject any changes to the ledger-specific portions of the Sovrin open source code by virtue of that role. They thus provide a counterbalance to the Sovrin architects who maintain the Indy code base.
