PyPI (Python Infrastructure): PyPI database issues
Timeline of updates
- resolved
Some slow Postgres queries combined with newer queries using the SERIALIZABLE isolation level led to high lock contention until we ran out of database connections. The offending queries have been fixed and the system is recovering.
From PyPI (Python Infrastructure)’s published incident history: for incidents before Rewindex began polling this status page, only the final update text is available.
Archive proof
Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert.
How the archive is checked, and what it cannot prove.
This incident predates live tracking (October 17, 2026). It came from the vendor’s own published history, which is not covered by checkpoints.
Impact, status and times are the vendor’s own, as last archived. View on status.python.org (opens in new tab).
