No new elsets appeared on OIG's database for three days from midday UTC
on Friday, but they are now flowing again.

SpaceCom's only current decay notice is:

Object                            Notice issued    Predicted decay

#25065 = ETS-7 H2 r               Jan 24 19:34     Jan 27 19:29 +-2d

My own analysis leads to decay at January 27.5 (~12:26 UTC +- 11h). 
This rocket enters eclipse near 27 deg S latitude at 20h local time and
leaves eclipse at 34 deg N at about 06h local time.
