Question About Iceweasel

[zephyr]

Good Morning,

I have been using Iceweasel 3.6.26~bpo~50+1. with Debain Lenny(oldstable)
Today when I did an apt update, I received the following message"
Failed to fetch 
http://mozilla.debian.net/dists/lenny-backports/iceweasel-3.6/binary-i386/Packages  
404 Not Found

Seems none of that location pertaining to Lenny (oldstable)is available.

Have you moved it ? Or, does someone else mirrored it?

It was there last week. Does this mean the end for iceweasel in Lenny?
