Smart Access Gateway (SAG) instances support temporary upgrades to handle traffic spikes.

Background information

You can temporarily upgrade the bandwidth of an SAG instance for a specific time period. After the temporary upgrade ends, the SAG instance is restored to the previous bandwidth. Rules of temporary upgrades:
  • The minimum upgrade duration is five days. Fees are incurred on an hourly basis. The upgraded bandwidth takes effect immediately after the payment is completed. Your workloads are not interrupted during the upgrade process.
  • After the temporary upgrade ends, the SAG instance is restored to the previous bandwidth. During the restoration process, your workloads are not interrupted. However, transient disconnections may occur when the bandwidth is being downgraded. We recommend that you ensure a reconnecting mechanism for back-end applications.
