Seconded. Yesterday I did not perform any update, so today there were offered again. The log ended with

2019-09-14 12:21:06 +0000 Notice -[TLMOperation main][1121]	Successfully executed `/Library/TeX/texbin/tlmgr --machine-readable --repository http://www.preining.info/tlgpg/ update --list --all`

and there was no spinning wheel, while yesterday there was only (say)

2019-09-13 13:37:42 +0000 Notice -[TLMOperation main][1133]	Successfully executed `/Library/TeX/texbin/tlmgr --machine-readable --repository http://ctan.math.utah.edu/ctan/tex-archive/systems/texlive/tlnet update --list --all`

and the wheel kept spinning forever.

So it seems the problem was really with Norbert's server.

First I did not understand what you meant by "separate asynchronous threads", but now I get it: reading the list of packages on CTAN's and Norbert's servers are independent tasks carried out in parallel. Yesterday TLU could reach CTAN's server but not Norbert's, hence the wheel that kept spinning. Today TLU can reach both servers, the order in which they appear in the log being immaterial.
