a) Create a pool that uses Global Availability as the load balancing method.
b) Assign your VS's to the pool, not as LTM related VS's, but as generic HTTP virtual servers. Put site1 as the first member in the pool, site2 as the second.
c) Create a custom HTTP monitor, looking for the string "site2 up", but make it a reverse monitor (meaning it will return 'Up' unless the target string is seen), and apply that monitor to the site1 VS.
This will have the effect of always using site1, unless the monitor returns the string "site2 up", at which point, the second pool member (the site2 member) will be used.
No need to use an iRule.
