Greetings,

The default TTL for DNS records was 48 hours; for people taking the
plunge and switching to navajos it makes for some painful debugging with
a TTL that high since you can't see your site on the new machine without
trickery for up to two days!

I looked about, and it appears that on the modern Internet a TTL over 24
hours is pointless and likely to be ignored, and that a TTL of around an
hour won't hurt anything. So, I set the default DNS TTL to 60 minutes
since everyone is going to have to migrate, and it'll minimize the time
your sites remain inaccessible.

If you've overloaded the TTL environment variable, you'll need to tweak
it yourself (naturally).

After the change propagates (which could take up to 24-48 hours) you'll
be able to access your sites on navajos within an hour at worst without
resorting to dns trickery.
