We are currently investigating an issue impacting the Data Modeling service (datamodelstorage) in the az-arn-001 cluster. A large spike in traffic against Data Modeling endpoints has led to an elevated rate of 503 errors (affecting roughly 3% of requests) in this cluster. Users and services interacting with Data Modeling endpoints may experience intermittent request failures. Our engineering team is actively investigating the cause of the errors and working on mitigation steps. Further updates will be provided as more information becomes available
