Relying on a DNS TTL of 5 minutes doesn't work everywhere. Some ISPs will forcefully reset any TTL below 24 hours to 24h.

AT&T/sbcglobal being one.
Absolutely true, and completely ridiculous. What, DNS bandwidth is too high? Please.
Well, not following the RFCs is bad, but I can see why they do it.
Most people using low TTLs probably don't know what they're doing, and if you're a big ISP having to constantly make recursive queries hurts page load times for your customers, who'll blame you.
