Capacity limits are physical, and we will tell you plainly when something is not available. Everything else — a larger volume, more instances at once, a higher API rate, a cluster wider than one node — is a message away. Tell us what you are running, the shape you need and the dates, through the contact form or a ticket in the console if you already have an account.
