So the question I then ask is whether or not the determination that the server is down is being performed using an authenticated or unauthenticated connection? Testing for "DOWN" should be performed using an unauthenticated connection specifically to avoid the problem of a "bad" token being installed into the client.
Servers can be marked down in either of two ways. First, there is a 3-minute cycle in which every known server is pinged by performing a GetTime call via an unauthenticated connection. Second, a server will be marked down if any RPC to it times out, or fails with an rx protocol error (small negative error code).
Normal errors, including RXKADEXPIRED and RXKADUNKNOWNKEY, _do not_ result in the server being marked down. However, rxkad errors (those whose values fall within the 'RXK' com_err table) will result in the users tokens being discarded.
