We are sorry for the inconvenience caused by the incident of 10/03/2020 between 10:20 and 12:08.
The service has been degraded on our platform for the following actions:
Cause: the submission of an email address is validated by a service provider. This one returned "invalid email" messages for the duration of the incident.
Correction: the service linked to this provider has been disconnected, only the format of the email addresses is validated (the domain name is no longer, and we no longer check whether the address is blacklisted).
This error is not technical, so it was not reported by our monitoring system, hence the duration of the incident.
Action to be taken: monitor this type of functional error from service providers.
