Greatings,
Since the other thread got closed I would like to create another one, please be contructive.
I know Zos is an American company, you provide a service for a lot of countrys and USA market is probably the most important to your business.
But planning a maintenance in labor day is just bad for a lot of us in Europe, I think americans wouldn't like to have a maintenance Semptember 1st ( and without knowing how much it will take)
You can manage a bit better you maintenance shedule, for example you could have patched the EU server today and the USA server tomorrow, this way almost everyone would have been happy.
