Cygwin.com address down

Cygwin list mailing list
Hi,

I tried installing cygwin on a new Windows 10 system yesterday and it
failed to find any mirror sites.

I can see www.cygwin.com to start the download, but then everything
points to cygwin.com and all those links fail (but work when I add
'www.' to the URL)

For example: The "mirrors" left menu link to
https://cygwin.com/mirrors.html fails but
https://www.cygwin.com/mirrors.html works

I will keep trying to see if it is back - or maybe everything should
just be pointing to the www.cygwin.com address.

regards

Peter Rice

Works for me (cygwin.com and www.cygwin.com both resolve to the same IP)
but there does seem to be some "interesting" routing going on and some
packet loss.  Here's the output from mtr

I suspect the problem is at flexential.net and will hopefully be
resolved soon.

Hi, I have the same problem - cygwin.org works for me, but cygwin.com
doesn't, although tester sites suggest cygwin.com is indeed up.

Since this looks to be some kind of DNS resolving issue for various
people, you can try to work around it by changing your DNS server
settings to use something like 8.8.8.8 and/or 1.1.1.1, which resolve
the names correctly.  Or, for someone just trying to get an install
done, a simple tweak of your /etc/hosts file to define the domains as
having IP 8.43.85.97 will work as a short-term fix.

This looks like perhaps a problem with a nameserver operated by BT, if
you are a customer of theirs.

Yes, I am with BT, so you're probably right. For the moment I've just
defined it manually in my hosts file.

I guess maybe I'll complain to BT then.
