Web services can be accessed in a number of different ways:

A webservices mailing list (with archive) is available. Users of these services are encouraged to sign up for the mailing list to receive announcements of services changes and interruptions, beta releases and to take part in discussions related to the services or ask for help.
For some additional background please read our newsletter article.
Real time data
All open data arriving in (near) real time at the IRIS DMC are available from the DMC’s SeedLink server.
The web services should not be used to retrieve continuous, real time data via repeated polling. Instead, the SeedLink server should be used when continuous data streams are needed.
