Still not the biggest black hole we know of. That would be Ton 618, weighing in at 66 billion suns. 30 billion is still ridiculously huge though. There are galaxies with less mass than that.

Wikipedia lists two bigger ones, but says the data is unreliable. Their estimated masses are greater than the theoretical maximum a black hole should have been able to reach in a universe this young.
