The container shortage and shipping slowdown (to get back to the op) is having a big effect on what I do as the shipping and logistics guy for our organization in PNG.
I've had to send out a few emails telling our people that shipping times have doubled, that available space will be limited to essentials, and that they may need to start buying their personal stuff here in country.
To make things even more fun, the US (and other) Postal Service still isn't' really delivering to the Asia-Pacific at the moment. Those packages get sent to New Zealand, thrown in a container, allowed to fill up, then is boated to POM.
DHL is working as normal, but ain't cheap.
