It has to do with random variance spikes in the times to find blocks. You can see different time averages at this site, the graph posted looks like a shorter term average like the 8 hr average:

So sometimes the overall network just gets fairly lucky for a few hours and finds lots of blocks more quickly than usual, leading to a higher estimated hashrate than really exists. OR maybe yes some huge farm just got turned on. You can't say for sure until you let more time go by and see what the longer time averages turn out to be.

OOooooh, good info. So when the hashrate is measured its not actually a measurement of the hashrate, its just saying how much faster or slower the network is getting blocks than it should? SORRY FOR THE FALSE ALARM ADAM
i almost shat myself.
Fact : Penguin shit is white. (apart from when it is pink... and well sometimes shit colour, but mostly white)
