In order to have a constant monitoring and overview of the status of the various services, as well as receiving a direct communication in case of incident (with clear statuses like "investigating", "resolved", ...) it would be extremely helpful to have a monitoring service in place. Other platforms are relying on something similar like the functionalities provided by Atlassian Statuspage. This feature gives a higher level of confidence to the merchants that have a direct and proactive communication regarding the status of the application.
