Using machines for load testing purposes

I would like to use Machines as part of the system creating artificial load on other systems (could be another service running on Fly or somewhere else), aka stress testing. The main goal is to pick a region or a series of regions, and send a steady (increasing) flow of HTTP requests against the given list of endpoints, without having to deal with provisioning of cloud instances (eg EC2, Droplets).

After checking the TOS, there does not seem to be any provisions agains running a service like that. Oh, and to clarify, all this is for internal purposes only, i’m not planning to provide this as a service to customers. Am i going to run into any issues? Ie Fly banning my (or associated) account for suspected DDOS?

Or would it be better to reach out to support and give a heads up about upcoming stress tests?
Thoughts / ideas?
