After four days of camping him! /cheer Yes, I named him Aslan.

I can also offer the following advice for my fellow Sambas Hunters-
x. He has at least a 12hr timer. The servers went back up at 1pm my time and I've heard that server restarts restart the timers on certain rare spawns, and I think this one's true because at 12:57 he was up and I managed the tame.
x. From what I can tell, Sambas is NOT phased if you're in the middle of the Twilight quests like I am. I leveled up to 85 and stopped what I was doing to hunt him, which was in the middle of the prep for the Dwarf wedding.
x. He was at the cords 68, 23, a cord that isn't listed on Wowhead, but a kind Petopian linked a Twilight rares cheat sheet with that point on it, so I knew to check there.

Hope that helps you all out!
