Sir... Uh... that's not how kernel fencing works.

Didn't know Tide pods came in orange.

OK, so I ended up moving www.kernel.org to be served via Fastly and it's working well. I will probably move it back once we figure out what this okhttp traffic is.

Jeg er veldig smart.

Don't ask me why I'm learning Norsk, it's a secret, but my Duo username may give a hint.

x.x.x.x - - [10/Nov/2024:00:02:37 +0000] "GET / HTTP/1.1" 301 162 "-" "okhttp/4.9.0"

You know whatโ€™s interesting about this log line? It repeats 56,686,963 times in www.kernel.org logs for yesterday, across 4 nodes. Thatโ€™s about 700 times a second, and this has been going on for months.

These requests arenโ€™t intentionally malicious โ€“ they issue a simple GET /, receive their 301 redirect, and terminate the connection. From what I can tell, this is some kind of appliance or software installed on mobile clients that uses โ€œcan I reach www.kernel.orgโ€ as a network test.

This wouldnโ€™t be that big of a deal โ€“ a single plaintext โ€œGET /โ€œ that triggers an immediate 301 is very cheap for us to generate, but the number of these requests has been steadily growing.

If you have any idea what this is and how to make it stop, please reach out?

Update to Fedora-41 was completely uneventful.

Not now honey. Daddy's checking to see if anyone liked the stupid joke he posted on the internet.

So, if mirrors.kernel.org went away...

The good news, they just keep a-coming, eh.

I guess we'll need to find a new home for kernel.org frontends by 2026.

I haven't been the most productive person over the past few days, but I think that describes most everyone's state of affairs. I'll try to catch up soon -- sorry if you've been waiting on me.

As a German, Iโ€™d recommend against voting for a dictator if thereโ€™s still another option.

Depending on the context, a "billion" can either mean "two million" or "half a million."
