 Even when some servers are available, it might not be possible to satisfy a request. For example, using [tag sets]({{< docsref "core/read-preference/#tag-sets" >}}) in a read preference when no server exists with those tags or attempting to write to a [replica set]({{< docsref "core/replication-introduction/" >}}) when the Primary is unavailable. Both of these would result in a [`TimeoutException`]({{< msdnref "system.timeoutexception" >}}). Below is an example exception (formatted for readability) when attempting to insert into a replica set without a primary.
