A comment on Understanding DNS Record Types.

A question regarding TTL. If changing the TTL value of a record will speed up (for want of a better word) when that record is available to the DNS server, why would you ever set the TTL to 3600 or more? I understand that there is some kind of caching going on but I don't actually fully understand TTL and what is ideal.

Any advice/insights/explanations appreciated!

A lot of that has to do with costs and service levels provided by your DNS provider. There's a couple of good points at Server Fault: http://serverfault.com/questions/388289/what-are-the-benefit...
