I am not sure if it is such a good idea to advertise a local mirror. Even if it is fast, you should not use it from remote locations, because this will put an unnecessary load on the network. At least that is how I learned the "Netiquette".
AFAIK, the beta's are distributed through most SUSE mirrors, so have a look here to find one that is close to you:
