What's Wrong with this Mirror?

[Chime Hart]

Hi All: As I run daily updates, I am noticing an error connecting to this 
mirror.
http://mirror.optus.net/deb-multimedia/dists/unstable/InRelease
Even just trying it in LYNX just hangs. Can some1 please suggest an adequate 
replacement for my sources list? This is Debian SID. Thanks so much in advance.
