Message Bus Reconnection
<p>I have slightly a weird question and it's for my clarity of understanding how message bus works.</p>

<p>Say suppose I have a message bus (from any vendor) and I have publishers and subscribers connected to the bus. Now as far as my understanding goes based on durable or non durable subscribers the published messages might be picked up when a subscriber reconnects(in case a subscriber was down when the message was published).I think I have some clarity on it(?).</p>

<p>Now say my message bus instance itself is down, for example when my publisher or subscriber connects to the bus, it is not able to connect to it or in other words the message bus instance virtually does not exist or has some internal issues.In this scenario will my messages be picked up the next time when the message bus comes up? </p>

<p>How is this scenario generally tackled while designing the system?</p>

<p>Thanks,
-Mike</p>
