What's "global traffic" mean here? Is it not about cars and transportations?

That's right! They're not talking about cars and transport. Here they're talking about "internet traffic," which is the flow of data within the internet. They also specify "global traffic," so it's the data flow around the world. Ex: The company carries the country's internet traffic. Ex: If servers are down, global internet traffic decreases.
