Investigating
We are investigating reports of issues accessing services hosted by our CDN when accessing via Anycast IPs.
Anycast is used for apex domains of python.org, pythonhosted.org, and pypi.org. Additionally users who query DNS from Google DNS and OpenDNS receive Anycast IPs in response for other services which are hosted by our CDN, as the provider cannot localize the result.
We are working with the CDN provider to determine what is causing this, and the scope of the impact is unclear.
