OK, I don't know what your business is but if your Internet connection is
'occasionally' going down then it's time you started looking for a better
provider. Depending on your business anything under 5 9's is unacceptable.
Here is another idea. Move the servers that cannot be down off site. There
are plenty of datacenters that provide 99.999% uptime.

If you know that your datacenter is going down more often then it should set
your TTL's a lot lower.
Smile... it increases your face value!
