SageMathCloud (<a href="https:&#x2F;&#x2F;cloud.sagemath.com" rel="nofollow">https:&#x2F;&#x2F;cloud.sagemath.com</a>), which was mentioned in the first line of the rackspace post, had 850 concurrent users at some point yesterday.  Our typical load is that high now.  I don&#x27;t think we&#x27;ve exceeded 1000 simultaneous users, but will likely do so in the next week or two.
