Hello WS users,

The issue described in the notification below has been resolved. Unfortunately the original notification was misdirected and never made it to the list :(

The short story is that the DMC’s fdsnws-dataselect web service will no longer accept HTTP HEAD requests, the response to such a request is now a 403 (Forbidden).

In the future we may allow the HEAD method again when we can handle them elegantly, although they are minimally useful since we do not include any of the HTTP headers normally interpreted from such a request.

Hello WS users,

Starting early this morning (Pacific time), the DMC’s web services have been only sporadically available.

We are currently working to determine the cause of the problem and, of course, a solution.

If you are currently accessing data via services you may need to resubmit your requests once the issue is resolved. If you are about to start some data requests, please wait until you here from us that the issue is resolved.

We will follow up with this thread when the service are operating normally again.

Thanks for your patience.
