Test case (Score 4, Insightful)

I'm a bit curious about this test case. It says the TTL was changed TO 24 hours and then checked to see how long it took for results to propogate. What was the TTL set to for these entries before the change? If it was set to 2 weeks and was just queried before the change occured, there is no reason for the server to recheck just because it was changed to 24 hours.

The TTL should stay the same for a while and then try simply making a change without modifying any other configuration to avoid any other problems with this test.
