I have 5 A741 hosted @ GND for a little over 1 month.  They were late putting them online (~15 days) due to too many new accounts and I've have some outages including current one for last few days.  All 5 dropped and 3 came back but still missing hash power of 2.

I hope that the frequent outages in the first month is just their new facility and that GND gives their customers days to replace installation delays & outages with extra hosting days.  I hope once they're done with their expansion that staff level will be able to handle support better.
