Our Spectra system is only used by an editorial team to produce Flat pages,
our site gets millions of hits an hour, therefore we don't serve Spectra
pages where we can get away with it,
We have a CF powered system for flattening pages on a schedule or on demand,
this work very well as when Spectra keels over, we still have a site.... It
also allows our growing editorial team to take advantage of clusted spectra
system.

Yes but only these, the child tags don't need Hacking ;)

Yes verity collections sit on the share

Ah... I understand now, by refreshing the site model beforehand it will
always make sure that it's got the most recent updates out of the db first.
More robust than me trying to notify all the servers that I think are
currently in the cluster.

So what do you do if the url param isn't provided? Not display anything or
maybe redirect to another member server?
Presumably you've had to hack cfa_page and cfa_container (and their
children) to achieve this?

Makes sense. What have you done about Verity collections? Do you keep local
copies of them on each machine or share them too?

Should be ok without it. I think I understand what's going on now.
