I assume time stamps are UTC, ftp shows 10/12/17, 10:12:00 PM, now it is Fri Oct 13 22:57:17 2017 UTC

I would say 24h+ update for such data is too much.

Also having signatures / checksums is a standard security measure for any downloads and are very easy to implement.

Hi Aliaksei

The files are regenerated daily. There are some checks done on the files as part of the generation process, like zero size check or size difference more than some percentage from yesterday. Perhaps the RIPE NCC can comment on the possibility of signing or checksum files?

Hello!

I would like to know if there is a plan to sign / checksum files located at
ftp://ftp.ripe.net/ripe/dbase/split/ ?
Currently there is no mechanism to know if files aren't tampered or corrupted.

My second question is how often those files are updated?

Thanks!
