[gnso-ff-pdp-may08] Use of short TTLs - one time events

[Marc Perkel <marc@xxxxxxxxxx>]

Just want to raise an issue about restrictions on short TTLs.

Every now and then I (and people like me) and doing some massive 
migration say from moving from one data center to another. Normally have 
high TTLs but the day before the move I might lower the TTLs to say 15 
minutes so that when the move occurs it can happen fast. After the move 
happens and everything is looking normal and stable then I put the TTLs 
back to normal.
In a case like this getting permission to have short TTLs would be 
somewhat burdensome. So I wanted to throw this in as an example of side 
effects of short TTLs.
So if there are TTL restrictions I'd like to see the system be smart so 
that if someone makes a few changes in a short amount of time - but it's 
a rare event - they can be distinguished for fast flux.
