Last week, November 23, 2022, IBM announced that on February 15, 2023, it will no longer be possible to download from the IBM Electronic Fix Distribution, IBM Electronic Customer Care, and IBM Fix Central using an unsecure connection:
IBM’s servers already support the encrypted download protocols:
HTTPSFTPS and SFTPDDPS
Your System Administrator should be able to easily make these changes well before the deadline. If they do not know how to make the change the announcement document gives them information of where they can go to get help.
IBM’s announcement document can be found here.
IMHO it is about time IBM makes this change from unencrypted to encrypted downloads, as just about all other vendors only offer encrypted downloads.
