!!SOAP Driver Retries
The SOAP driver will issue a "retry" status on the following HTTP result
codes by default: 307, 404, 408, 503, 504.

Additionally, the list of HTTP codes that result in a retry status is
configurable. So, to answer your question, yes, if the HTTP server is
unavailable or the connection becomes interrupted, it would result in the
event being retried later.
