PyPI
PyPI is the official Python Package Index, hosting over half a million open-source libraries that developers install via pip.
What is PyPI?
PyPI — the Python Package Index — is the canonical repository for Python software packages, serving as the infrastructure that makes "pip install" work for every Python developer in the world. Governed by the Python Software Foundation and founded in 2003, PyPI hosts hundreds of thousands of packages ranging from NumPy and Django to one-off utilities written by individual developers. The index processes billions of download requests monthly, with peaks during CI/CD pipeline runs and developer workstation setup. The Warehouse codebase, which is the modern PyPI implementation, replaced the legacy infrastructure beginning in 2018 after years of volunteer-driven maintenance.
The platform's architecture separates package index metadata storage from package file distribution. Metadata (package names, versions, dependencies) is served from PyPI's web servers backed by a PostgreSQL database. Package files (.tar.gz and .whl distributions) are stored in Amazon S3 and served through a Fastly CDN layer, which handles the enormous download traffic without it hitting PyPI's origin servers directly. The upload API is used by package maintainers (via twine or CI integrations) to publish new releases. Authentication uses API tokens with configurable scopes — project-specific tokens are the recommended pattern for CI pipelines. The Simple API (PEP 503) is the machine-readable interface that pip uses to discover available versions and download URLs.
PyPI outages are acutely felt across the Python ecosystem because package installation is embedded in so many automated workflows. CI/CD pipelines that run "pip install -r requirements.txt" at the start of every build fail completely — every build across every project that hits PyPI at that moment breaks simultaneously, across millions of pipelines at companies and open-source projects worldwide. Developer workstation setup becomes impossible for anyone bootstrapping a new environment. Docker image builds fail at the layer where Python dependencies are installed. Package upload failures block release pipelines for library maintainers trying to ship new versions. Unlike an application outage that affects end users of a specific product, a PyPI outage affects developers and build systems as the primary impact class.

Frequently Asked Questions
Common questions about PyPI outages and server status.
You can check the live PyPI server status at outage.gg/services/pypi. The page shows real-time community-submitted outage reports, an hourly trend chart, and the current health status.
PyPI can stop working for a number of reasons including scheduled maintenance windows, unexpected server failures, network infrastructure problems, or DDoS attacks. Check the live status page on Outage.gg for the latest community reports to see if others are experiencing the same issue.
Go to outage.gg/services/pypi and click the "Report an Issue" button. Your report is counted immediately and helps confirm whether a problem is widespread. Reports from multiple users trigger a status change visible to everyone watching the page.
Click the "Notify Me" bell button on the PyPI status page at outage.gg/services/pypi. Create a free account and we will send you an email the moment PyPI comes back online — no app download required.
Many services maintain official status pages with planned maintenance notices. Outage.gg aggregates real-time community-reported outages which often surface faster than official channels.
