I am using the latest version 2.0.3.1 of OC and I have noticed that some times,
the store gets in "Offline - Maintainance Mode", without me setting this option.
Any ideas why this can occur

Can this be the result of a hack / attack or is there any mis-configuration that can bring this result

It is pretty annoying to see that store becomes unavailable on its own and
it seems to happen often, so give any advice or how I can monitor why/when this happens

Thanks, looking forward for your insight on this!
