At 11:00 UTC on 18 June 2020, FTP access to jsimpson will no longer be possible.  The stoppage was originally scheduled for 1 June 2020 but due to the impacts of the CoVid19 pandemic, the end of FTP was delayed. 

Effective 11:00 UTC 18 June 2020, both jsimpson.pps.eosdis.nasa.gov and jsimpsonftps.eosdis.nasa.gov will provide FTPS access to GPM NRT data.

FTPS will be the main, 24hr/7day retrieval protocol for getting GPM NRT data from PPS.  Remember PPS implements explicit FTPS, FTPS retrieval will require your system administrators to open ports 64000-65000.  You can find examples of using curl and wget for FTPS access to data on jsimpson in

          /NRTPUB/documentation/FTP-FTPS-Transition.pdf

As secondary access to GPM NRT data, PPS also provides a HTTPS REST service at https://jsimpsonhttps.pps.eosdis.nasa.gov/text.
Documentation for this access is available at /NRTPUB/documentation/ jsimpsonhttps_retrieval.pdf.  This will provide documentation of the service as well as examples of use.

While PPS will attempt to minimize the downtime of jsimpsonhttps, it can not guarantee the same uptime as the FTPS service. There may be times, because of maintenance requirements for the Apache server where the downtime may be to up 24 hours.

It is STRONGLY recommended that you use FTPS to access the data if you require high uptime and low latency.

NO FTP AT ALL AFTER 11:00 UTC 18 June 2020. This can not be delayed further.
