Summary

On Thursday Nov 9th the default certificate for the external Nginx ingress was replaced with a dummy certificate. Users attempting to reach their hosted instances would get an invalid certificate error. This was due to a misconfiguration in the new CI for releasing our helm charts that used the internal Nginx ingress values files for the external Nginx ingress.

Impact

All hosted customers not using custom domains were affected.

How was the root cause diagnosed?

We identified that the values were properly set in the values files. We Investigated the CI steps to determine why the correct values were not set. It was determined that the wrong values files were being used for external Nginx ingress.

How we’ll make this not happen again?

• Update staging and production value files to match.
• Add alert to pagerduty for non-custom domains (catch alerts faster)
