Network HasRate gained more than 30% in the last hours 
30% is not so little. Are you sure? To me it looks network hash rate is between 460 and 470 MH/s what is close to what it was last few months.

Monero mining subredit is totally calm. So I am skeptical you are right.
Well, on monero.how the hashrate was in the morning at 350, now it's at 470...
Maybe monero.how is lacking some info...
