Scheduled

We will be performing scheduled maintenance on our Kafka infrastructure in the EU region. This maintenance will only impact the EU cluster.

During this window, you may experience the following:
* Ingest will remain uninterrupted - events will continue to be accepted, although their processing will be delayed. You may notice a gap in your data during the migration window; this data will be backfilled after the migration completes. Expect all data to be present within approximately 3 hours of the maintenance window closing.
* Query results will reflect a delay in fresh data during the cutover window, in line with the ingestion delays.
* Triggers and alerts: Triggers watching for missing events (e.g. heartbeats) will fire during this window. Triggers watching for values above a threshold are not expected to fire. Other alerting sources will process delayed events late, up to approximately 3 hours.
* SLO burn alerts will also fire late during this window.
* Activity Log and Service Maps will experience delays in processing events.

We appreciate your patience and will provide updates as the maintenance progresses
