Monitoring
MailChimp API error rates have dropped significantly over the last three hours. Configuration of *new* MailChimp integrations, as well as lead delivery to MailChimp appear to recovered to some degree.
If you have encountered an error during configuration of a MailChimp integration during the last day or so - you may be in a state that requires intervention on our side - please reach out to support if you suspect this is the case for you. Similarly, if you are seeing delays in lead delivery to MailChimp, we may need to remediate this on our side.
We have not yet received positive confirmation from MailChimp support that the problem has been resolved on their end - as such, we will continue to monitor the problem overnight and update the incident once we're confident that the problem has been resolved.
