Hi Bryan,
I don't think it is important to be available 24x7. I hope (probably is
not developed, but will be pretty simple to do) that the Gateway caches
the last registry document found, so that it can be still restarted
without problem if precisely at that moment PCMDI's central registry is
not available.
The worst case scenario would be if someone wants to install a Gateway
anew and at precisely that moment the registry is down. this could be
solved by packing a "pre-cached" version of the registry with it (not
that I think this will be that important, as adding this new Gateway to
the federation will take time).
So while the server is down, no new Gateway can be added to the
federation, nor any other changes be done. But the federation itself
should work without a hitch.
But perhaps I'm missing something here...
Thanks,
Estani
