gmail regurlarly going down

It seems more frequently that gmail is having problems with connections.

I have got a "really" theory in that Google is so technically advanced that is splits up processing applications based on needs and the processing power is all in one grid.

So areas like google search, gmail, blogger search have less priority then adsense. As more people take up adsense it is taking up more of the Googles technical resources which is effecting the performance of its other tools
