It's just that depending on routing, different connectivity might
connect your IMAP client to a different data center and back-end server,
too, which may sidestep the bug depending on the provider's server-side
deployment schemes and schedules... meaning to say it's not as
deterministic to outsiders as it may seem at first glance.
