I think there's a way to see which cdn mirror you are hitting when you ask for "www.kernel.org". Konstantin, any hints as to see if maybe one of the mirrors is out of sync?
Looks like the Singapore mirror was feeling out-of-sorts. It'll start feeling better shortly.
Great, thanks for looking into this!
BTW, the easiest way to figure out which frontend you're hitting is to look at the output of "host www.kernel.org", e.g.:
$ host www.kernel.org www.kernel.org is an alias for git.kernel.org. git.kernel.org is an alias for ord.git.kernel.org. ord.git.kernel.org has address 147.75.58.133 ord.git.kernel.org has IPv6 address 2604:1380:4020:600::1
The three-letter airport code should indicate where the frontend is located (in my case, ORD = Chicago). There are total of 6:
sea.git.kernel.org - Seattle lax.git.kernel.org - Los Angeles ord.git.kernel.org - Chicago fra.git.kernel.org - Frankfurt sin.git.kernel.org - Singapore syd.git.kernel.org - Sydney
Geodns magic should send you to the nearest one, and if the monitoring recognizes that one of them is down, it will be automatically removed from the pool until it recovers.
