Looks like it.

Yet I am able to reach your mirror with my browser, but (again from my
home machine):

iPanic:Music ralph$ curl http://mirror.lihnidos.org/CentOS/timestamp.txt
curl: (6) Couldn't resolve host 'mirror.lihnidos.org'
iPanic:Music ralph$

Looks like I only get the AAAA address. Home machine is OS X, mirror
checker is CentOS.

Cheers,
