Hosting
Fly.io
Fly.io deploys containerized full-stack apps across a global network of edge servers, placing compute close to users for low latency.
What is Fly.io?
Is Fly.io down? Fly.io is a global application deployment platform developed by Fly.io Inc., founded in 2017 and headquartered in Chicago, Illinois. It allows developers to deploy containerized applications close to their users across a network of data centers in over 35 regions worldwide, with features like automatic global distribution, persistent volumes, private networking, and Machines—lightweight micro-VMs based on Firecracker. Developers and startups increasingly use Fly.io as their primary hosting platform, so any outage or server issues can take production applications offline across multiple regions simultaneously.
Fly.io's control plane orchestrates the lifecycle of Fly Machines—creating, starting, stopping, and scaling them in response to traffic and configuration changes. The platform depends on a globally distributed Anycast network for routing user traffic to the nearest healthy machine, and on its API servers for flyctl CLI operations and webhook-driven deployments. Regional network partitions, control plane API degradation, or failures in the WireGuard-based private networking layer that connects machines across regions are common sources of complex, multi-symptom incidents.
When Fly.io is down or not working, users commonly report that deployed apps return 503 errors as Fly's Anycast proxy cannot reach healthy Machine instances, flyctl commands like fly deploy or fly status hang indefinitely without returning output, Fly Machines that should auto-start in response to incoming traffic remain stopped causing cold-start failures, persistent volume mounts fail to attach causing stateful apps like databases to crash on restart, and the Fly.io dashboard at fly.io/dashboard shows application metrics as unavailable with an API connectivity warning.
