I have a private Django webapp going to production this week and was testing some fly deploys. The fly machines, db, and any other external services are located in SIN. There is only one test user and they are located in Southeast Asia.
About 10 min after successful deployment, I noticed in Grafana that there was about 200mb of data out to IAD on the edge cloud.
Question - does Fly send any data to the IAD datacenter during the build process? Is there anything in the fly deploy process that might explain this unknown data outbound to IAD?
