What happens if I exceed my max connection creation rate?

Some connections will be refused and the client will receive a 429 error. As with other 4xx errors, the client will not retry by default. In this scenario, you should get the client to reattempt connection.


If this is a regular occurrence then you should consider increasing your peak connections to increase the creation rate limit as per the limits calculator. Please see our pricing page to change this on your package. For business or enterprise account, please contact your Account Executive to preprovision an increased rate if you are having an event.
