Additional capacity was added to our redis caches. This triggered a failover between UTC 15:10 - 15:14 and there was a spike of errors on the REST and GraphQL APIs. Customers would have seen some errors in the Buildkite UI during this period as well. We have been monitoring the situation since then and things have returned to baseline.
