In April-May 2017, all PDA Users were provided with expanded ranges of
IP Address for their interfaces to PDA at NSOF, CBU, and (where
applicable) I&T. We originally requested that the new PDA addresses be
added to any applicable firewall rules and systems by the end of June
2017 to ensure continued access to data from PDA. For any new
interfaces
established as of about March 2017, these addresses were incorporated
into the original set of IPs you were provided, so would not require
additional changes. This effects all FTPS and SFTP data transfers that
connect to the PDA/ESPDS DMZ (internal connections, including ESPC,
DCS,
GOES-R, JPSS, and CLASS) are not affected by the additional data
servers) and all internal interfaces that utilize web services
via HTTPS.
On October 23 2017, new PDA servers are scheduled to be deployed to all
environments as a part of PDA/ESPDS Release 3. Once that deployment is
complete, any external interfaces that have not yet incorporated the
additional IP addresses may experience intermittent connection errors,
when your data transfers are load balanced to the new Data
Servers. More
specifically, users who push data to or pull data from PDA
(i.e. clients
to ESPDS), will experience intermittent connection failures,
while users
whom PDA pushed data to or pulls data from (i.e., servers to ESPDS) may
experience gaps in data and PDA will experience the connection
failures.
How to know if you have the full list in your firewalls? For regular
DMZ
consumers, there are 25 IP addresses for NSOF and 25 IPs for CBU. For
push data providers, there are 19 IPs at NSOF and 16 IPs at CBU.
If you have any questions or concerns about your system's readiness for
the additional ESPDS IP Addresses, please contact
Emmanuel.Addo@noaa.gov
or Jennifer.Holmes@noaa.gov.
