I was listening to 13760 kHz today which is the first of two frequencies for Europe & at 1350 hrs UTC it suddenly went off air in the middle of a song. I checked the 2nd frequency for Europe, 15245 kHz, & it was still on air. Likely they are still having power related issues. Not the first time I heard VOK fall off the air.
13760 did come back on air a while after, although other times it stays off for the rest of the day.
