When using the GraphQL endpoints on Fauna, you may very rarely see an error that the service is currently unavailable. This can happen if the service has received too many requests in a very short period of time. The usual workaround if this happens is to simply retry the query; it should succeed on the subsequent attempt. As an additional safeguard you can loop the retry, however we recommend no more than a maximum of five automatic retries. If the query errors out after the fifth retry, we encourage you to open a ticket with our Support team.
