From approximately 13:32 UTC to 14:14 UTC, there was a partial read outage of Loki-managed recording rules. Customers in the prod-us-west-0 region may have experienced gaps in recording rules and alerts configured with Loki.
Engineering has released a fix and as of 22:30 UTC, customers should no longer experience errors accessing instance us-east-0. At this time, we are considering this issue resolved. No further updates.
