If you look at the hashrate numbers, it increased from 2,411,623,656 GH/s on 10th January to 2,812,940,600 GH/s you need a lot of miners to make this jump. Bitmain started to sell its new T9, its possible that one of the bigs farms received a lot of these new miners. Also Bitmain could start mining on its new farm.
Those numbers still look moderate if we compare them with the growth in prices all of a sudden.
This is just the beginning of a new era in mining, we are possibly heading towards a considerable amount of high-quality mining where it will be impossible for an average miner to even think of it.
