I mentioned this on the BLFS support mailing list. The issue is a very
widespread and ongoing DDoS attack against GNU and FSF sites. As a work
around, there are a few options.

1. You could manually update the URL in your wget commands to use the
mirrors provided by LFS, assuming you are building from a stable book.
2. You could also manually update the URL in your wget commands to use
https://ftpmirror.gnu.org. That site is a mirror selector for GNU, and will
auto resolve to a mirror site.
3. You could also manually update the URL to use a mirror listed on the GNU
site instead of using the mirror selector.

From what was said in response to my report on the BLFS mailing list, it is
a known issue, and the LFS team has been in contact with the FSF/GNU team.

Here is a link, provided in my report to BLFS support by Rainer, that
details some of the issue GNU and the FSF are facing at the moment.

I hope one of the suggestions above can help you retrieve the sources you
need.

Thanks,
Eric
