So according to
blockchain.com and their way to evaluate it, a new (daily) ATH has been reached, but my point was to show the discrepancy between the news from the Daily Mail and the reality, not to announce a record breaking.
Sorry but that's exactly what you did, you announced a record-breaking hashrate:
The Bitcoin hashrate has reached a new ATH
You looked at the 7-day average and took that as a record while that average comes from this: (switch to raw)
The average in those last 7 days was actually high because of the days of 1st and 2nd, as you can see there is clearly a downtrend from that record, so you're actually acknowledging that the hashrate is dropping from an ATH.
Data becomes reliable when you go over longer periods, that's why we have an adjustment in 2016 and not after 6 blocks.
Yes you're right I've been misled by the post from mably I quoted. Actually the daily ATH seems to have been reached several days ago, the 1st january. It reached 207.53 EH/s, and it dropped to 170-180 EH/s the next days(unless those figures are
totally unreliable 
). Then even if this ATH seems to be a spike, there is actually a decrease from the top.
