Okay I did some digging and came up with the following:
The instancing was working perfectly fine a week ago. As of the last time we handed off to another guild in the North American rotation they got a fresh instance that was neither ours nor the Asian guilds so it WAS possible to have more than two instances a week ago.
In the interim apparently some guilds, by accidently spawning new instances when the wrong person clicked over first, found out how to reliably spawn new instances whenever they wanted and were clearing Time (or at least as many of the gods as they could) nearly everday despite the longer respawn timer.
My guess is that they partially disabled the instancing to prevent this from happening and figured that TWO was enough simultaneous instances to keep around since that would allow a NA guild and a Euro/Asian guild to both use it...only they didnt account for a) Tunare having THREE guilds and b) the determination of which instance anyone gets to be messed up... so now we have all kinds of problems !
Its really very frustrating
