How long until .ly domains disappear?

It would seem with nic.ly offline most of the time, that registrations aren't possible. However, Thomas mentioned that there does seem to be periodic activity between the primary and secondaries, so in theory Libyan Spider could connect and push to nic.ly.

Seems like someone, or several someones, are managing this pretty well. I think we're ok, but there is a risk it'll go away if they shut it down.
