On August 28, 2008 the Strategic Rocket Forces conducted a successful launch of a Topol (SS-25) missile. The launch took place at 14:36 MSK (10:36 UTC) from the Plesetsk test site. The Rocket Forces reported that the warhead successfully reached its intended target at the Kura test site in Kamchatka.

The missile that was tested had been in service for 21 years. Most likely it was deployed with the missile division in Novosibirsk - the crews of the Glukhov Guard Missile Division based in Novosibirsk were reported to be leaving for the test site earlier this week. The press-release mentioned an "experimental warhead" (which, of course, would be able to defeat all possible missile defenses). My guess would be that these might be some new decoys or penetration aids - these are normally deployed with all Russian missiles.

UPDATE 09/05/08: According to another report the launch was performed by the crews of the Yoshkar-Ola division.
