1. Your transit bill grows faster than your revenue
If your upstream invoices rise every quarter, look at where the traffic is going. For most access networks, a large share goes to a small number of content, video and cloud platforms. Those platforms are often present at exchanges. Every gigabit you exchange with them directly is a gigabit you no longer pay transit for.
2. Customers complain at peak hours
Evening slowdowns are a classic sign of congested upstream links. Adding peering capacity moves the heaviest flows onto direct paths, relieving pressure on transit.
3. You already run BGP with your own ASN
If you multi-home or announce your own prefixes today, you have the technical foundation. Joining an exchange is an incremental step, not a new discipline.
4. The content you carry is already nearby
Large platforms increasingly place caches and points of presence in regional cities. If they are at an exchange near you, the opportunity is sitting next door.
5. You want a second path to critical destinations
An exchange gives you an independent route to many destinations. If an upstream has an outage or a fibre cut, peering keeps a large portion of your traffic flowing.
6. You have downstream networks of your own
If smaller ISPs, enterprises or campuses buy connectivity from you, peering lets you offer them better performance to popular destinations — a competitive advantage.
7. You are planning for growth
Transit is priced per megabit. Peering is priced per port. As traffic grows, the economics of peering improve while transit costs keep climbing.
Doing the maths
A simple model: estimate the share of your peak traffic that goes to networks present at the exchange, multiply by your transit price, and compare it with the monthly cost of the port and cross-connect. For many regional ISPs, the port pays for itself early — and the performance benefits come on top.
