Curious. What method do you use to connect to such a large number of instances? I'm assuming you're sending identical commands to them all at once through an SSH client, but I also assume you didn't cut and paste 1000 different IP's into the SSH client to make the initial connections.

Following this thread over the past couple weeks has been a great learning experience when it comes to VPS mining techniques. Thanks to those who have shared experiences here. Those were just the threads I needed to pull in Google searches to get better set up for Zcash mining.
