- Around line 15-24: Update the HTTP handler in TestInstancesSecondPage to
return an empty servers response for requests to zones other than the test’s
target zone. Keep the two-page server fixtures only for that target zone so the
collected IPs match the test expectation.

Filter the fixture to one zone.
GetResource requests all eight scw.AllZones. The handler returns both servers for every zone, so ips contains 16 addresses while ElementsMatch expects two. Return an empty response for non-target zones.
