Modal
Modal is a serverless cloud platform for Python developers that makes it easy to run GPU workloads, batch jobs, and scheduled functions without managing infrastructure.
What is Modal?
Modal was founded in 2021 with an unusual goal: make cloud infrastructure invisible to Python developers. The product's design allows developers to run Python functions in the cloud by decorating them with a single @app.function() decorator, with Modal handling container provisioning, dependency installation, scaling, and GPU allocation entirely transparently. The developer experience removes the operational overhead that normally sits between a Python function and cloud execution — no Dockerfile, no Kubernetes manifest, no infrastructure configuration beyond specifying resource requirements. That simplicity has attracted ML engineers and data scientists who want cloud compute without becoming cloud infrastructure operators.
Modal's runtime provisions containers on demand and scales them to zero between invocations, making it well suited for inference endpoints that have variable traffic and would waste money on always-on reserved capacity. The SDK supports GPU-accelerated containers with NVIDIA A10 and A100 instances, persistent volumes for model weight storage, web endpoints that expose Python functions as HTTP APIs, and scheduled functions that run on cron schedules. The modal deploy command pushes code to Modal's infrastructure, making the deployment model similar to serverless function platforms but with much higher resource limits and Python-native semantics.
Modal service disruptions surface in ways specific to the serverless execution model. Container cold starts increase significantly during infrastructure load events, causing the first invocation after a scale-from-zero event to take much longer than the p99 baseline — a problem that manifests as user-visible latency spikes for inference API endpoints. The Modal CLI fails to connect to the control plane during backend issues, blocking code deploys and function invocations initiated through the SDK. GPU container provisioning failures cause @app.function() calls with GPU requirements to fail with capacity errors rather than waiting to scale, breaking inference pipelines that depend on GPU availability. Volume mount failures prevent containers from accessing stored model weights, causing inference functions to fail at startup rather than at the model loading step.
Outage.gg tracks Modal service status using real-time community reports from ML engineers and Python developers. If function invocations are failing, deploys are not completing, or GPU container provisioning is broken, the live status page shows current impact from the Modal user community.
Common Modal Problems
Issues users most frequently report when Modal is having problems.
Service unavailability
API calls are failing, dashboards are unreachable, or the service is returning 5xx errors.
Slow performance / high latency
Response times are significantly above normal, causing timeouts and degraded user experience.
Authentication failures
API keys, OAuth tokens, or SSO logins are being rejected unexpectedly.
Data sync & storage issues
Files, databases, or synced data are not updating, missing, or inaccessible.
