Sometimes folks have too long a TTL on their DNS records, but yours seem fine. Helps to be able to get traffic directed elsewhere faster should you need it (given your setup I doubt you'll do much better for scalability than edge-cached static CDN content). Short TTLs aren't a sure thing, but can help. Recommend they be lengthened again once things are stable to be a better internet citizen.
