UDP broadcast spamming on VPS

Web VPS

So there's this guy on the same node as I and two days ago he started broadcast-spamming UDP packets to port 1900 like a madman to all VPS' on the same node and the provider tells me that this is completely normal.

Shouldn't there be some sort of isolation on layer 4 and upwards? What do you think?
