[webservices] Retirement of deprecated services and new service locations

[Chad Trabant]

Hi web service users,

If you have not updated your data requests to use our new services instead of the deprecated services please do so immediately.  We are only days away from shutting down the old service end-points.

Java and MATLAB users:
If you have used the DMC’s IRIS-WS library (or our irisFetch.m MATLAB interface) make sure you are using 2.0.4 (or later) to avoid problems with updates we plan on making in January.

regards,
IRIS DMC

The equivalent DMC services are now deprecated and will be retired, read more on that below.

Programs that access data via these FDSN web services should also be compatible with any other data center implementing FDSN interfaces.  There are a few, clearly marked IRIS extensions to the functionality that may not be implemented elsewhere.

For example, the time series web service now supports wildcards, and much more flexibility in selection style (supporting both GET and POST submissions and comma separated lists for channel name fields).
