Possible delays for surface mail items (Suez Canal incident)

[SpacePhoenix]

How much of a delay will we probably see with surface mail items (no idea how much goes through it) that pass through the Suez Canal? If you've not seen it in the news, the https://en.wikipedia.org/wiki/Ever_Given lost power and run around and is now blocking the canal, from side to side.

I'm guessing that a good chunk of the packets from China probably pass through the canal (some of them might well be stuck on the Ever Given)
