To help reduce latency (here comes the speculation), the scheduler then shuts down the other instances and reopens them closer to the new location. I wouldn't worry about it too much; I see this phenomenon happen occasionally, as well as other strangeness with instance restarting. If you look back in this forum's archives you'll see similar stories. Most likely the scheduler has decided that you'll get better performance if it moves you to a different location; if you're not seeing any major latency or RPC issues, I'd ignore it for now and periodically monitor the issue. ----------------- -Vinny P Technology & Media Consultant Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
