           Are there any pricing differences between Cloud Services (classic) and Cloud Services (extended support)?
         answer: |
           Cloud Services (extended support) uses Azure Key Vault and Basic (ARM) Public IP addresses. Customers requiring certificates need to use Azure Key Vault for certificate management ([learn more](https://azure.microsoft.com/pricing/details/key-vault/) about Azure Key Vault pricing.)  Each Public IP address for Cloud Services (extended support) is charged separately ([learn more](https://azure.microsoft.com/pricing/details/ip-addresses/) about Public IP Address pricing.)

+          Why do I see a change in billing amount after November 2022 for Cloud Services (extended support) deployments ?
+        answer: |
+          A bug in Bandwidth billing was fixed in November 2022, resulting in customers possibly seeing increased billing based on their data transfer out to other regions or internet. For additional reference, visit the [Azure bandwidth pricing page](https://azure.microsoft.com/pricing/details/bandwidth/).
