No. Amazon gives you an A record and asks you to make a CNAME for it. So when they change an ELB's IP, they update their A record. So in our case, we just make sure our A records follow along. Either way, a DNS cache holding onto a stale record too long would cause a problem. Which is why Amazon keeps the ELB active on both the old and new IPs for a period of time. |
