Knowing if Briz-KM failed for a final deorbiting burn will not be easy. And more difficult due to the military nature of the mission. But if a final failure accured "leaks" from unofficial sources in russian space industry will tell us in the next days.

What the heck is all that orange smoke coming around it, doesn't look healthy?
its normal around the ignition and early launch portion of the flight. It is un-ignited propellant and is a common site for hypergolic boosters.
Thanks. I don't remember seeing anything quite so orange on other launchers, is it something that comes from the fact that it is converted ICBM?
it partly has to do with fact that Rockot still uses its silo launch tube above ground and that there is not a flame trench for deflection so it just kind of hangs around. You will see it with Proton to if you watch the flame trench cameras when ignition occurs.
Also Rockot is from UR Booster family in the UR-100 subfamily and uses the same fuel and oxidizer.
Thanks for that explanation.

Since the launch was at 16h25 GMT, it was a night launch.

Sounds like the Russians have confirmed that something went wrong with the retro-burn of the Briz-KM, as they have delayed the next Rokot launch to June because of "launch vehicle problems":

According to Izvestia, the satellites did not reach the intended orbit and only two of the three Rodnik-satellites could be activated while the third is considered a loss.

I had a look at their orbits on Heavens Above; in terms of apogee, perigee and inclination they look fine compared to other Rodnik satellites launched. Jonathan's SATCAT shows the Briz-KM in a comparable orbit, so if a failure occurred I doubt it affected the satellites' orbits.
If one of the satellites "couldn't be activated", that would suggest a spacecraft problem rather than a launch problem. If the Briz failed I strongly suspect it was between s/c sep and a disposal burn.

At closer look, the problem is more on Izvestia's journalism

Kosmos-2483 have not yet performed maneuvers unlike Kosmos-2482 and Kosmos-2484.

Is it possibly failed or do you think it might not be going to the similar location as the others.

It possibly failed because the Russian MoD possibly can not control it after dirty separation from Briz-KM and followed tumbling.

Did the Briz-KM also tumble; why it did not perform final manoeuvre?

Briz-KM shortly after sep went into a safe mode and did not execute de orbit burn or the CCAM maneuver. That is only information I have come across so far, but it is main source of Rockot delays besides SC issues for upcoming missions this year.
