Location of NCBI ftp site changed?

Question

[sampsa.hyvamaki]

Hey,

The NCBI ftp site that was previously found from https://ftp.ncbi.nih.gov/ seems to have moved to https://ftp.ncbi.nlm.nih.gov/

I tried to find official announcements of the change from blog posts but was not able to find any.

Does anyone know if this change was announced somewhere?

Thank you in advance!

Both links should work.

A DNS query shows that they are aliases (I have redacted actual IP addresses).

$ host ftp.ncbi.nih.gov
ftp.ncbi.nih.gov is an alias for ftp.ncbi.nlm.nih.gov.
ftp.ncbi.nlm.nih.gov is an alias for ftp.wip.ncbi.nlm.nih.gov.
ftp.wip.ncbi.nlm.nih.gov has address xxx
ftp.wip.ncbi.nlm.nih.gov has address xx
ftp.wip.ncbi.nlm.nih.gov has IPv6 address xx
ftp.wip.ncbi.nlm.nih.gov has IPv6 address xx

$ host ftp.ncbi.nlm.nih.gov
ftp.ncbi.nlm.nih.gov is an alias for ftp.wip.ncbi.nlm.nih.gov.
ftp.wip.ncbi.nlm.nih.gov has address xx
ftp.wip.ncbi.nlm.nih.gov has address xx
ftp.wip.ncbi.nlm.nih.gov has IPv6 address xx
ftp.wip.ncbi.nlm.nih.gov has IPv6 address xx

Thank you, it appears that my system is not able to resolve the CNAME record chain.

The following page has a mention of ftp.ncbi.nlm.nih.gov being the preferred location:

https://www.ncbi.nlm.nih.gov/genome/doc/ftpfaq/#basepath

(this makes sense as CNAME chaining uses more DNS resources).
