1. postmortemOct 24, 2022, 15:44 UTC

   ## Summary The cluster that hosts PyPI’s backends as well as multiple ancillary services experienced an outage during maintenance that interrupted access to services over HTTPS. ## Details From 2022-10-24 14:43 UTC until 2022-10-24 15:03 UTC, PyPI’s backends were not accessible over HTTPS. This interfered with our CDNs ability to fetch pages, made uploads to [uploads.pypi.org](http://uploads.pypi.org) impossible, and interrupted other services such as our legacy file redirect service. PyPI services run as deployments in a Kubernetes cluster and are exposed via Ingress with the AWS Elastic Load Balancer \(ELB\) integration. The TLS certificate that this load balancer uses is managed via Amazon’s Certificate Manager \(ACM\). When initially deploying our Kubernetes cluster, the Ingress managed ELB was configured to use an existing ACM TLS certificate. Earlier today, regular maintenance of our Kubernetes cluster required a rolling restart of all nodes in the cluster to distrib
