When you think about it, your network is a lot like the road to a small town on the cusp of an incredible population explosion. There’s a nice infrastructure supporting the small amount of people leaving and returning, and that’s all that’s needed.
As more people find out about this wonderful place, the town grows and that two-lane highway can’t support the influx of new people making their lives there. Suddenly there are traffic snarls, roads are constantly in disrepair and trash is strewn everywhere.
