Our system continually monitors the bandwidth usage of all our VPS. In case if your total monthly bandwidth usage reaches to 85-90%, you will receive alerts. If however, your VPS exceeds its allocated monthly bandwidth limit, you will receive an invoice for additional bandwidth usage. You can make the payment against additional bandwidth usage invoice within day or two. In case you fail to make the payment, we will suspend your VPS service until your bandwidth counter resets to zero i.e. 1st of every month. If your bandwidth usage is higher, we suggest you to purchase additional bandwidth upfront at the cost of $20 / month per 100 GB.
