Neo4j aura restarting instances

I'm running Neo4j Aura on GCP and I recently had an outage that seems to have started with a bunch of SHOW DATABASE system YIELD address followed by ENABLE SERVER $id then a 100% CPU spike for a few minutes and all connections dropping. Then it came up again. I don't see anything else out of the ordinary in the logs. Any tips on what is going on and how I might debug it further?
