Looks like hashrate is back up.

there is no evidence the hashrate ever fell

it cannot go "back up" if it did not even fall

Maybe I'm missing something, but it looks to me like there were only 114 blocks mined on 9/23.

596163 to 596276

100EH/s at 11.8T diff should produce 170 blocks/day on average. If the nethash was actually at 100EH/s, the probability of getting 114 blocks is .00000319. Pretty unlikely.
90EH/s at 11.8T diff would average 153 blocks/day. Probability of 114 blocks is 0.000587, which is getting into the range of possibility, but still a once in a 5 year kind of event.

Probability of getting <= X number of blocks in a day at 100EH/sec:

If we calculate profitability comparing to hash rate against the price of BTC, then it is trending in negative values.

So, many user especially miners supporting BTC are moving towards alternative coins to generate with their hash power. This is the main reason behind the falling of hash rate of BTC mining.

BTC is always a prime cryptocurrency among the market, based on the SHA-256 algorithm which is supported by ASIC mining.

Next wave hash rate will be gone higher as halving is coming by next year.
