Summary of Impact:
At approximately 10:14 UTC on Friday 6th May 2022, we detected issues communicating with Google BigQuery. This caused delays in refreshing segments and running programs in our North America region. The issue was resolved around 14:46 UTC on Friday 6th May.
This was caused by an issue with multiple Google Cloud infrastructure components. The impact of the affected Google services can be seen here.

We depend on Google’s BigQuery service for some aspects of our functionality and have configured multi region support to increase availability. In this case a failure in a single region caused BigQuery to fail despite other US regions being online. We’re working with Google to understand why this occurred.
