AWS Network Limits and Limitations¶.
By default, your consumers access the service with that DNS name and … Why did this slowdown happen? If you want to set alerts for cost overruns or spikes, you need to look into the Billing controls. We traced the issue to the DNS infrastructure we operate on the Amazon Web Services (AWS) platform. DNS queries exceeding these limits are dropped. These names include the VPC endpoint ID, the Availability Zone name and Region Name, for example, vpce-1234-abcdev-us-east-1.vpce-svc-123345.us-east-1.vpce.amazonaws.com. If AWS needs any extra information they will ask you for the same before increasing your limits. We're not capping costs, just adding some protections.
