Our fdsnws-station web service, the primary source of station metadata for our seismological repository, is moving from service.iris.edu to service.earthscope.org as part of our cloud transition.

We’ve worked to make this transition seamless, but if you encounter issues please contact help@earthscope.org.

The service documentation contains the most up-to-date information regarding changes to the service.

Phased rollout

The transition will take place in two phases:

• Soft launch (17 June, 2026) — The service becomes available at its new location, https://service.earthscope.org/fdsnws/station/1/. The existing service at service.iris.edu continues to operate unchanged during this transition period, allowing users to test and migrate to the new endpoint at their convenience.
• Redirect (29 June, 2026) — Requests to https://service.iris.edu/fdsnws/station/1/ will redirect to https://service.earthscope.org/fdsnws/station/1/. The vast majority of web software follow these redirects automatically or can be configured to do so.

Breaking changes and additional capabilities in the new service

Along with the move, the new service includes the following changes:

• Availability removed — The new service no longer supports the inclusion of data availability. The includeavailability and matchtimeseries parameters are no longer supported and will return an HTTP 410 Gone response if these parameters are submitted.
• New resp output format — The format=resp output is fully compatible with the dedicated irisws-resp (https://service.iris.edu/irisws/resp/1/) service.  Requires level=response.
• New sacpz output format — The format=sacpz output is fully compatible with the dedicated irisws-sacpz (https://service.iris.edu/irisws/sacpz/1/) service

Future consolidation of the resp and sacpz services

Over time, the fdsnws-station service will become the single source for these products, replacing the standalone “irisws” services:

• level=response&output=resp will ultimately replace the irisws-resp service (https://service.iris.edu/irisws/resp/1/).
• level=response&output=sacpz will ultimately replace the irisws-sacpz service (https://service.iris.edu/irisws/sacpz/1/).

More details for client developers and power users

We recommend that client developers and power users update any hard-coded references to point to the new endpoint at https://service.earthscope.org/fdsnws/station/1 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 this new service.
