Bug Summary

Received by email:

We (NCEDC) recently started using https (from http) for FDSN webservice and this would make an error when obspy users will use Client("NCEDC") as shown at the bottom of the email. A simple tentative solution to work around this issue is to overwrite URL_MAPPINGS:

from obspy.clients.fdsn.header import URL_MAPPINGS
URL_MAPPINGS['NCEDC'] = "https://service.ncedc.org/"

We will post this at the front page of the NCEDC website so that users can get our data with obspy but eventually it would be great if obspy source code will use "https://service.ncedc.org/". Could you please pass this information to the obspy developer team?

Thank you so much again for providing obspy (and MSNoise indeed!) to the community. Please let me know if you have questions.
