What's really important are our Seed Nodes. The more we have and the more distributed they are the better. I was just wondering about how distributed our network was last week and actually investigated it and did up a report which you can find here.

We're currently not very well distributed with most nodes sitting in France, Germany and the US. Even with this type of consolidation all three countries would have to target those nodes at the same time to bring the Steem blockchain down. If they did we'd only have a few scattered nodes around the other countries that the whole network would be relying on. Likelihood of this happening is extremely low, but it'd be nice to see our blockchain network branch out and grow some more.
