Google Fiber comes back to life with 5 gigabit service, plans for 8Gbps soon

Lets start taking bets for how long it will last this time.

I'll bet a dollar on 9-12 months... :)

Why 8Gbps? Seems like an odd number when SFP models generally are 10, 25, 40, 100.

80% loading of a link is where queuing theory says latency goes up fast. With 10Gbps links (be they 10Gbps ethernet links or XGSPON), you don't really want to go up above 80% load. 10Gbps PON is becoming mainstream now, while 25Gbps PON is still only in early testing at this point.
