Beginning January 8, 2021, Dynamic Route for CDN (DCDN) uses the pay-by-data-transfer metering method by default. After DCDN is activated, the metering method cannot be changed in the DCDN console. If your DCDN service was activated before January 8, 2021 and uses the pay-by-peak-bandwidth metering method, you can continue using this metering method.
