Noticed it because snap didn't work, snap has its own status page just fyi: https://status.snapcraft.io/

Frustrating because the Slack snap is broken so every day you have to downgrade it and I guess you can't without connectivity. This might be the incentive I need to finally purge snap.

Just move to flatpak, much nicer to deal with

Tinfoil hat mode: a competitor wants to exploit copy.fail on some ubuntu servers, and is DDoSing canonical so that they can't update and thus patch the vuln

If you can access AF_ALG on a server you don't need to do shenanigans like that. It's much easier to just find another bug and exploit that one instead.

The copy.fail website is very silly, it is not a special bug. If anyone gets compromised by that vuln their node architecture was broken anyway, patching copy.fail doesn't help.

I thought copy.fail is a privelage escalation exploit, become root from a regular user? Am I missing something?

How would "node architecture" make people vulnerable to this?

You have to have shell access to a victim first right? Or am I missing something?

Though this outage may be more related to the copy.fail upgrade cycle, it reminds me of a thought I've had recently in respect of agents.

In the UK they have this issue called "TV pickup" (https://en.wikipedia.org/wiki/TV_pickup). TV pickup is where everyone in the UK watching a popular TV show gets up to boil a high-powered tea kettle at the same time on an ad break. This causes a temporary surge in electricity demand and leads to real outages. It was a mystery at first but now is accounted for.

I suspect the global internet is facing an "agent pickup" problem where significant changes (e.g., releases of new frontier models or new package versions) puts unpredictable pressure on arbitrary infrastructure as millions of distributed agents act to address the change simultaneously.

In what way is it "not a special bug"? It's a publicly known root access from RCE exploit. Those cannot be a dime a dozen. I'm sure it's especially interesting for any shared hosting services which might be affected, and could be delayed. I could find any places running containered services and exfiltrate secrets parallel services, no?

What constitutes "special" for you, out of curiosity? Something chaining with a hypervisor exploit?

In my testing I find the exact reverse. I much prefer snap to flatpak.

We're at the stage where we blame AI for anything as a first reaction?

(Love the tv pickup story. I also thought of that, in other situations)
