Open the load balancer → Resize tab in my.cubepath.com.

Compares your current plan against the others available in the same location, showing each one's max targets, max listeners and connections per second, plus its hourly and monthly price. You can move up or down.

Which limit are you actually hitting

The three limits fail in completely different ways, so identify the right one before you pay for a bigger plan:

LimitSymptom
Connections per secondNew connections refused at peak while existing ones keep working. Users see intermittent failures that vanish when they retry
Max targetsYou simply can't add another backend server
Max listenersYou can't add another port or service to this load balancer

Check the connections-per-second chart on Metrics against the plan's ceiling. If your peak isn't near it, a bigger plan won't make anything faster — the bottleneck is in your backends.
