Switching to Flat Rate CDN for Pro teams saves a lot of billing
For those who aren't familiar, this covers everything from Fast Data Transfer and Blob Data Transfer to the actual CDN requests and those observability events that usually sneak up on you in the logs. The most important thing to realize here is that the capacity is managed at the team level, not the project level. This means if you have five different projects under one Pro account and one of them suddenly goes viral, it will eat into the total allowance for the entire team.
The numbers for the Pro tier are pretty specific: you get 1 TB of data transfer and 1 million requests per month. If you're running a small-to-medium site, that's usually plenty. If you hit that ceiling, you have to upgrade to a higher tier to get more capacity.
How to handle the transition
If you're starting a new Pro team, this is already the default. However, if you've been around for a while, you're probably still on the usage-based model. You can find the toggle in the Billing settings to switch over.
The "Spike Protection" feature is the real winner here. It's enabled by default, meaning if you suddenly exceed your tier's capacity, your site doesn't just crash or throttle—it keeps serving traffic normally. As long as you're following the fair use guidelines, you aren't billed extra for that overage, which is a huge relief for anyone deploying an AI workflow or a public API that might see erratic traffic.
Real-world deployment tip
When setting this up, I recommend auditing your current usage logs first. Since the capacity is shared across the team, you should check which projects are your "heavy lifters." If you have one project that consistently hits 800GB of transfer, you're leaving very little room for your other apps.
To check your current consumption and see if you'll fit within the 1 TB limit, you can usually run a quick check on your analytics dashboard. If you see your daily average is over 30GB, you're cutting it close to that 1TB monthly limit.
This setup is much more beginner-friendly for teams who are just scaling up. Instead of calculating costs per request or per GB, you just know what your monthly burn is. It simplifies the AI workflow for developers who want to focus on building features rather than monitoring a billing dashboard every hour.
For those of us who hate the "pay-as-you-go" gamble, this is a much cleaner way to handle deployment. You just set your tier, deploy your assets, and stop worrying about the cost of every single request.
