Incoming webhooks and Bitrix24 uptime?

Question

Bitrix24

If you actively use the Bitrix24 service and set up data transfer from the outside with the help of incoming webhooks, you probably noticed that sometimes developers roll out new functions to the cloud B24 or, as a result of malfunctions, the service is down.
If at this moment the form on the site through the rest api tries to send data to you in CRM, then they will still get there (after all, in fact, we don’t see the layer there and suddenly there is something somewhere first for such cases "settles" ) or will they still be lost (but I can’t check it, because I can’t manually “put” it for tests)?
If they are lost, then what did you do (I understand that this is entirely a matter of personal fantasy, but all the same, suddenly someone will share their best practices)?
