GoKawiilPyPI Fixes Two-Week File Download Outage Tied to Fastly CDN Bugs
PyPI experienced intermittent 502 and 503 errors on files.pythonhosted.org for about two weeks in August 2026, breaking package installations for some users. Investigation traced the issue to a Fastly canary deployment that misconfigured a single cache node, plus separate longstanding bugs in PyPI's Fastly setup around origin fallback and range requests. Both issues were resolved, with downloads fully restored by August 28.
