There have been a few crashes. About four, depending how you count them. The longest was a few hours as it happened during my night. Others were about 30 minutes and 90 minutes in length. And the fourth, a period of about five hours in which the grid acted funky in several ways, including a couple of crashes (which only lasted a couple minutes each time as I was inworld when they happened).
The causes? No common or apparent or repeat theme/problem. Which is good news and bad, lol.
With the above exceptions, the grid has been running 24/7. The only problems I know of are the ones I have encountered firsthand. I would love to hear from visitors who have any trouble.

Last fall, I had the grid online for several weeks before my PC had unrelated troubles. Again,. "the grid" is actually a standalone. At that time, I was running 17 regions on a five-year old PC. Now I am running 25 regions on a brand new PC. Otherwise, there is little difference in the operation. It seems to be running smoothly now with the above noted exceptions...but last fall, it ran completely without incident. I would say it ran better then, than now. Is that because of the additional eight regions? Maybe. Maybe not.
I did try in my testing last month to increase the grid to 38 regions. It crashed three times in one day during the uploading of large OARs. I could have investigated and tested further to see if a standalone on this PC can work at that size...but my reasons for considering that many regions had actually become moot, I was just trying it for the heck of it! So I just lopped off a bunch of regions and tried again at 25. It's running fine so I'm going to stay with that number for now. If things change, I will simply eliminate a few more regions as 25 is still more than I need. But again, what the heck? I know 17 regions worked well, I'm just testing it at 25 for now. :)
Last fall I had four regions on Kitely, now I have 30. So the final number of regions on Dankoville doesn't matter to me. I just want as many as I can get without causing poor performance.
