Hello libtool maintainers,

Our project uses the `libtool` package, which is vendored via `conan` as
defined in this conancenter recipe [link to recipe
<https://github.com/conan-io/conan-center-index/blob/master/recipes/libtool/all/conandata.yml#L3>].
Recently, all of our builds have been failing when attempting to build the
`libtool` package for our target architecture. This is due to an inability
to fetch the source code from `https://ftp.gnu.org/gnu/libtool`.

Many of our builds originate from the same public IP address
(15.205.200.76), which fronts our corporate network. We suspect this IP
address might be part of a larger CIDR block that has been blocked.

If this is the case, *could you please allow-list our IP address,
15.205.200.76?*

Thank you for your assistance.

Best regards,
Michael Fedell

The ftp.gnu.org server was overwhelmed with too many requests last week
and it is very likely that we noticed that IP as one which had many
requests and fit a pattern that did not make sense to give priority to.

https://raw.githubusercontent.com/conan-io/conan-center-index/master/recipes/libtool/all/conandata.yml

In the above yaml, there are links to ftp.gnu.org, but they should be to
to ftpmirror.gnu.org. The bottom of the page at https://ftp.gnu.org
mentions the mirror system and links to http://www.gnu.org/prep/ftp.html
for more information. That is the system we rely on for serving files
far beyond the FSF's own bandwidth.

That will solve your immediate problem, but downloading the same files
hundreds of times into the same local network is not great, it is
unnecessarily using other people's bandwidth which costs them
money. There are 2 good things you can do about this. 1: you could keep
a local cache. 2: you could host a gnu ftp mirror yourself, reducing the
load on other mirrors. If other people are downloading from your mirror
more than you are downloading from other mirrors, then it would be much
more reasonable to be downloading the same file many times over.

Since the IP blocks are not a bug with GNU Libtool specifically, closing.
