If you wish to receive announcements about changes in data management and services, you can subscribe to the Data Announcements mailing list.
The following web services are moving from service.iris.edu to service.earthscope.org as part of our cloud transition: irisws-syngine (the primary source of customizable synthetic seismograms for arbitrary source-receiver configurations), irisws-fedcatalog (a federated discovery tool designed to help users locate seismic time-series data across multiple FDSN data centers), and irisws-nrl (the primary source of instrument response information).
We’ve worked to make this transition seamless, but if you encounter issues please contact us.
The service documentation for irisws-syngine, irisws-fedcatalog, and irisws-nrl contains the most up-to-date information regarding changes to each service.
Phased Rollout
On August 20, 2026, the services will become available at their new locations:
- https://service.earthscope.org/irisws/syngine/1/
- https://service.earthscope.org/irisws/fedcatalog/1/
- https://service.earthscope.org/irisws/nrl/1/
The existing services at service.iris.edu will continue to operate unchanged during this transition period, allowing users to test and migrate to the new endpoint at their convenience.
On August 24, 2026, requests to the service.iris.edu locations of these services (https://service.iris.edu/irisws/syngine/1/, https://service.iris.edu/irisws/fedcatalog/1/, and https://service.iris.edu/irisws/nrl/1/) will redirect to the new service.earthscope.org locations. The vast majority of web software follow these redirects automatically or can be configured to do so.
We recommend that client developers and power users update any hard-coded references to point to the new service.earthscope.org endpoints rather than relying on the redirect from the old location.
Please reach out to help@earthscope.org if you have any questions or run into trouble with these new services.
