Speed up DNS resolution

RE: Speed up DNS resolution
Your best bets are to:
- Use a DNS service that uses Anycast for their servers
- Make sure the DNS provider has servers distributed globally (and that perform well)
- Try to avoid long CNAME chains (try to avoid them at all if possible)
- Use a long Time To Live (TTL) on your records so they can be cached by the ISPs and users

Glue records are really meant just for the name server IP's. Using them for normal records may provide faster performance in some cases but it's really not the intended use and they are quite a bear to change (and propagating the change can take days).
