I don't know the exact reason for this increase, but I don't think this is something out of the ordinary. If I'm not mistaken the "normal/default" mempool cap is something like 300 MB, but of course, this is up to each node individually, as there is no such thing as universal mempool. If you take a look at the yearly chart,

https://www.blockchain.com/it/charts/mempool-size?timespan=1year

you will see that there have been larger mempool sizes in the past.

Sorry now I see ... it can be a good signal but not really so exceptional

I think it is better to use https://jochen-hoenicke.de/queue/#1,24h.
Here you can see that what's taking most of the space are 1sat/byte tx (latest graph).
The space occupied by higher fees transactions is minimal compared to the space taken by the 1sat/byte ...

Usually this means that a big exchange is consolidating its UTXOs.
Looking into the queue today I noticed some heavy tx from Bitmex and Luno.

They can stay in the queue for a while, miners will mine higher fees transactions first
and eventually mine these only when nothing left to mine remains in the queue.
