Outage: Julia package server offline [resolved]

Status: Resolved


Around 2023-03-06T08:16:00Z the DNS resolver for the package servers went offline.


As a temporary measure we are resolving the DNS names for the pkgservers directly. This minimizes impact while we are working on resolving the core issue.


Impacted users can set the environment variable JULIA_PKG_SERVER="" to bypass the pkgservers.
Please remember to unset the environment variable after the outage has been resolved.


At 2023-03-06T15:40:00Z the load balancing DNS server resumed functionality and full service was restored.

Next steps

This outage highlighted a single point of failure in our pkgserver infrastructure. We will add fallback servers to avoid future outages.
