The signal from GLONASS-M No. 734 disappeared on April 19, later the communication with GLONASS-M No. 723 was lost. GLONASS now has 22 satellites - to cover Russian territory, they need 18 operating satellites, while for the whole planet 24 are needed.

Is there any public info what caused them to fail?

Since some days 734 transmits signals again, still wrong / unhealthy.
He should be put back into operation, but still be replaced by 756 and then go into reserve.
