It was more a brainstorming question Innula, sorry for my misleading answer.
Dirk suggested a dashboard for sim restart. I like the idea, but paranoia will impeach it for sure.
I have asked to at least have a reliable site where exact status of sims is allowed for residents or at least for region owners.
Presently, one of my regions shows up on map, but this is false. From aside it is invisible, it is not possible to teleport, my in sim surveyors are dead. Wath map shows is fake. I got one time the answer that is was a viewer issue from Lindens. The llRequestSimulator data or gives no answer of give also false answer "region status up", while it is completely dead and inaccessible.
As for support, during work hours and working days, live chat works as they can. they have to refer to "engineers", and it often takes a day. Submitting ticket, takes a day. On week end, it is according to the weather !
I dont' see any justification for a region to be down : there are roll restarts each week. The region in default is working 5 days a week, and all activieties have of course disapeared from it.
I am sure that this is not an isolated case, and that LLs are not managing the situation. And support absent during week end, when activity is major, what joke is this !
