It's called random variance. There is a drop, but it isn't to 124eh
That site does not understand statistics, which is mandatory for anyone trying to estimate the global Bitcoin hashrate.
As is typical of many sites who really don't know what they are doing, there is no error range shown on their graph, which since it's daily, that error range will be high.
Firstly, as explained here,
https://bitcointalk.org/index.php?topic=5307087.msg56342703#msg56342703if you use 250 blocks to estimate the Bitcoin network hash rate, you have a 42.9% chance of being more than 5% wrong.
With only a smaller sample of 1 day (expected 144 blocks) it a higher chance of being more than 5% wrong.
Also, I can't find 124eh anywhere recently on that graph.
in this graph on the lowerside has option 30days 60days etc. Check the 30days
also in the right side has option raw value-7 day average-30 day average : check the raw values.
there you will see the drop of 124eh.
am not defending that site just mentioning the drop.
also today saw in the news problems with the Sichuan distict with power.
so the breaking news that china bans bitcoin for the 99th time this year is a fact
