AWS Support announces three new AWS Trusted Advisor checks that offer best practices for using Amazon Route 53. Trusted Advisor now provides 30 checks for major AWS services, including EC2, S3, EBS, RDS, ELB, and Route 53. The new checks are:

  • Amazon Route 53 Alias Resource Record Sets (Performance category): This check identifies opportunities to use alias resource record sets to route DNS queries to AWS resources. Using alias resource record sets is the most efficient way to route to AWS resources, and the routing is free of charge.
  • Amazon Route 53 High TTL Resource Record Sets (Fault Tolerance category): This check examines resource record sets that can benefit from having a lower time-to-live (TTL) value. A long TTL can cause unnecessary delays in rerouting traffic.
  • Amazon Route 53 Name Server Delegations (Fault Tolerance category): This check examines Amazon Route 53 hosted zones for which your domain registrar or DNS is not using the correct Route 53 name servers. Correct configuration helps to ensure maximum availability.
