Read and write path outage in Hosted Logs ap-south-1 region cells.

Incident Report for Grafana Cloud

Resolved

The incident was caused by multiple ingesters being unavailable at the same time due to moving ingester pods between nodes. It's a regular operation, but in this particular case the ingester took an unexpected long time to restart which coincided with another ingester eventually restarting at the same time, causing an issue.
