The zone for monstermarket.example is live. The shop runs on web-1 and web-2 behind market-alb. shop.monstermarket.example is a failover pair: the load balancer as primary with the health check shop-alb, and a "back soon" page in the S3 website bucket shop.monstermarket.example as secondary.

1. Customers at http://shop.monstermarket.example/ get the back-soon page, although the shop answers at the load balancer's own address. Find out why and fix it, without touching the records.
2. api.monstermarket.example is a weighted record set old (weight 90) for the API's old fleet at 192.0.2.10. The new fleet answers at 192.0.2.30. Without changing old, make the new fleet get one answer in four, with a TTL of 60.
3. Answer the question about game day before you start it.
4. Game day: stop web-1 and web-2. Customers must get the back-soon page, with nothing changed in DNS.
