Hybrid model¶
The flagship Rubin Science Platform (RSP) at data.lsst.cloud is a hybrid deployment, with services and data distributed across multiple data centers:
Most of the services and some data are hosted on the Google Cloud Platform.
A few services and most of the data are hosted at our US Data Facility (USDF) at SLAC.
This architecture provides flexibility and performance while controlling storage costs.
When an outage occurs, service and data availability can be affected differently depending on which data center is impacted. During LSST Data Previews, the RSP does not yet provide detailed error messages from its services. This page provides guidance on what to expect when USDF/SLAC is offline and how to continue using the RSP during such outages.
