Current issue with ObsPy FDSN web service client

November 1, 2022

11/22/2022 Note: This issue has been fixed in ObsPy v1.4.0.

In order to enhance security on our web services, we are now enforcing https connection. Even though most clients do support the redirect from http to https, there seems to be an issue with Obspy. We have contacted the developers and in the meantime, users can apply the following workaround before calling the Client() function:

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

FTP service to be retired on May 31, 2022

May 9, 2022

After May 31, 2022, the NCEDC will no longer be offering FTP services for researchers. We will continue to offer HTTPS as a way to download the same content. Researchers with automated scripts involving FTP will want to update their scripts to change any paths following the example below:

ftp://ncedc.org/pub is available as https://ncedc.org/pub
ftp://ncedc.org/outgoing is available as https://ncedc.org/outgoing

Note that URLs with ftp in their path (such as https://ncedc.org/ftp/pub/) will also be deprecated on May 31, 2022.
