ROOT CAUSE
30% of our ingest servers restarted concurrently, causing ingest load balancing issues and resource constraints.
RESOLUTION
Kentik Operations allowed the servers to come back online, monitored the automated restart of all Kentik software, and tracked the reestablishment of BGP sessions with any peerings that flapped.
Additional ingest capacity will be brought online by 2022-10-14 to help alleviate these types of scenarios in the future.
