The fourth burn occurred, but produced goofy results. Guidance?
Ed, it's premature to speculate, but I can't help wondering if this isn't another perfectly healthy vehicle flown into the ground [soon, will be] by human error in the loaded burn parameters?
Other wild speculations...
What commonality do we have with the 3Glonass splash? Both errors may intersect at the pad 31 prop loading complex.
According to the Proton user guide, Briz-M prop loading happens in Building 92A-50.
Are your sure? It seems to me that Briz-M fueling happens at the "service station" out of the building 92A-50, so there is no commonality with the 3 glonass fail.
Block DM03 was fueled elsewhere.
Briz-M has both high and low pressure tanks.

7.5.1 LV Processing
The Proton LV stages, PLA, and fairings are built in Moscow by KhSC and transported by rail to the Baikonur Cosmodrome. After transportation of the Proton’s stages and fairing by rail, LV assembly takes place in an
integration and test facility. Prior to SC arrival, the fairing is moved to Building 92A-50 for SC integration, where it is stored and cleaned in preparation for encapsulation. The Breeze M US is manufactured by KhSC in Moscow and transported by air to Baikonur. After arrival, the Breeze M is delivered to Building 92A-50 for pre-launch checkout and testing. The Breeze M is then delivered to Building 44 in Area 31, the propellant fueling hall, where MMH and N2O4 are loaded in the high pressure tanks of the low-thrust settling/attitude control system thrusters. The Breeze M helium pressurant tanks are also loaded in Building 44. Following these operations the Breeze M is then moved to Building 92A-50 for integration with the SC. Payload adapters are similarly delivered to Building 92A-50, where they are cleaned and prepared for assembly of the AU.
6.1.3 Breeze M Fueling Station (Area 92)
The ILV will be transported to the Breeze M fueling facility for filling the Breeze M with low pressure propellant components, and from there to the launch complex (Area 81 or 200).

Aha! Thanks!
Same facility which mis-loaded the prop on the DM3 that splashed the Glonass triplet.

As for DM-03 upper stage, 1.5 tonnes over-fuelling of liquid oxygen was made on the launch pad.

Apparently, the wanted injection orbit was 5210 x 35786 km x 20.5°

Good info on fueling locations, thanks.
Bldg 92-50 was a real mystery when we visited in mid-1990s, it was new but empty, with wide staircases leading from the ground floor DOWNwards. Interesting wall murals [local artist quality] of military-looking spacecraft, probably just impressionistic rather than descriptive.
did you post any pics? would enjoy seeing them.

I seem to have been trapped in an out-of-date concept of the Blok DM propellants. Anik, thanks for banging on my head until the new data could seep in. My bad.

This section of the Proton user manual has not been posted here:
6.3 BREEZE M FUELING FACILITY
Following final assembly, the ILV is transported from Building 92A-50 to the Breeze M fueling facility. The fueling facility is located in Area 92, directly adjoining Building 92A-50, with some 70 m distance between the building and the facility’s external fencing. The fueling facility has been upgraded and reequipped to satisfy the needs of the SC manufacturers and contractors, and is capable of supporting any operation required for
SC health checkout and SC on-board storage battery recharging during the ILV stay at the facility. The fueling facility is used for filling Breeze M tanks with propellant components at low-pressure (high pressure components are filled earlier at Area 31).

Yes, it is fueling station 11Г12, located less than 100 meters in front of MIK-40.

With the latest elset, I found
Epoch August 19 at 1659UTC:
EXPRESS-AM4/11045A in 1004.5 x 20314.9 km inclined 51.33°
Epoch August 19 at 1301UTC:
Briz-M / 11045B in 697.2 x 20239.3 km inclined 51.18°
The expected orbit after Burn 4 was to have been 420 x 35,616 km x 49.1 deg.

Ed,
Do you know the other target orbits?
Stan
173 x 173 km, 270 x 4998 km

Interfax-Ukraine reports on August 22 // 1416 UT
"The Ukrainian system for control and analysis of conditions in space (SKAKO) has tracked Russian Ekspress-AM4 telecommunications satellite."
"According to [the Agency representative], the launch elements were tracked by SKAKO early on 21 August with the following parameters: spacecraft Ekspress-AM4: 20,312 km apogee altitude, 994 km perigee altitude, 51,3 degree angle; fuel compartment of the Briz-M upper stage: 11,294 km apogee altitude, 146 km perigee altitude, 49,5 degree angle."
Further, "Movement parameters of these space objects are confirmed by astronomic measurements of the optic devices of the State Space Agency of Ukraine. In order to determine the condition of the space objects in orbit, photometric measurements are being made," he (the Agency representative) said.

Press release by Roscosmos
http://www.federalspace.ru/main.php?id=2&nid=17756Google translation
August 18 from Baikonur cosmodrome launch vehicle (LV), "Proton-M" with the upper block (RB) "Breeze-M" and the spacecraft (SC) "Express-AM4."
Home and flight "Proton-M" were normally, in accordance with the scheduled program.
During the flight, the orbital block in the upper stage and spacecraft crashed into the control system "Breeze-M", as a result of the «Express-AM4" was put on an unplanned orbit.
Means of space control systems (SKKP) Russian Space Forces Defense Command and Aerospace Defense of North America (NORAD) were able to establish the parameters of the orbit of the spacecraft (inclination - 51.23 deg., Apogee - 20,294 km, perigee - 995 km, orbital period - 368.39 min.).
Representatives of the Federal Space Agency, Ministry of Communications of Russia (Federal State Unitary Enterprise "Space Communication") and the company EADS Astrium have been made joint efforts to establish contact with the spacecraft in order to enable its onboard systems.
Now experts are continuing to establish communications with the spacecraft.
Formed a joint working group to identify opportunities for the transfer of a spacecraft into orbit and then use for their intended purpose, subject to inclusion of on-board systems.
Interministerial Commission for the analysis of the causes of abnormal start-up carrier rocket "Proton-M" with the upper stage "Briz-M" and the spacecraft "Express-AM4 continues. We consider several possible reasons for this situation, most of which - the failure of the control system booster.
Work in preparation for launches of carrier rockets "Proton-M" and boosters "Breeze-M" temporarily suspended until the establishment and elimination of causes abnormal spacecraft into orbit, "Express-AM4."

AFAIU, a more precise translation would be:
