openSUSE admin

Tumbleweed updates, and attempts to "zypper ref", have been consistently
failing for me on more than just one system since 2023-11-28Tue15:54:28
central time usa. Meanwhile other users report success and no trouble,
suggesting perhaps some sort of trouble with automated mirror redirecting.
Surprisingly tho it even fails for me if i specify mirrors directly. FFI
