Which makes a client error less likely. It may mean it is a problem with
proxies, load balancers, some DNS, or your routers. The latter would
imply that the address on at least one side is local to you, which is
reasonably easy to verify. DNS errors might be harder to check - but
lookups on the local DNS of the affected clients ought to give a
misdirection to your site at least in some instances, if you do them
reasonably close to the event. To eliminate proxies (or to put a name to
the responsible software), you could log the proxy via's. If it should
be a transparent proxy or load distributor, that won't help though.
