Topic: Certificate updates affecting FTPS users require verification testing at CBU site

Date/Time Issued: April 23, 2020 1834Z

Product(s) or Data Impacted: All products transferred via the FTPS communication protocol

Date/Time of Initial Impact: April 23, 2020 1900Z

Date/Time of Expected End: April 27, 2020 1900Z

Length of Event: 96 hours

Details/Specifics of Change: The ESPC PDA system at the CBU site has updated certificate trust stores that can affect FTPS communications under some conditions. The PDA Support Team is Highly Recommending that FTPS users test communications with the CBU site ASAP before Tuesday April 28, 2020, when the updated certificates must be implemented at the NSOF OPS site. Communication testing can start immediately. The two part scenario that causes failed FTPS communications is 1) the users system is set to not ignore SSL certificate errors, and 2) the user does not trust the Active DoD SW CA 53 signing authority that the new certificates are signed by. The combination of these two issues may result in communication negotiation failures.

If negotiation failures are found during testing, please send an email to PDA_DHS@noaa.gov for further instruction. The PDA Support team will respond to your email Monday – Friday during normal business hours of 08:00 am EDT – 05:00 pm EDT.
