Engineers have been vibe coding a lot recently...

The featured blog post where one of their senior engineering PMs presented an allegedly "production grade" Matrix implementation, in which authentication was stubbed out as a TODO, says it all really. I'm glad a quarter of the internet is in such responsible hands.

Thats a classic claude move, even the new sonnet 4.6 still does this.

is this blog post LLM generated? the explanation makes no sense: > Because the client is passing pending_delete with no value, the result of Query().Get(“pending_delete”) here will be an empty string (“”), so the API server interprets this as a request for all BYOIP prefixes instead of just those prefixes that were supposed to be removed. The system interpreted this as all returned prefixes being queued for deletion.…

yep, no mention that re-advertised prefixes would be withdrawn again as well during the entire impact even after they shut it down.

I do not work in the space at all, but it seems like Cloudflare has been having more network disruptions lately than they used to. To anyone who deals with this sort of thing, is that just recency bias?

It has been roughly speaking five and a half years since the IPO. The original CTO (John Graham-Cumming) left about a year ago.

They coasted on momentum for half a year. I don't even think it says anything negative about the current CTO, but more of what an exception JGC is relative to what is normal. A CTO leaving would never show up the next day in the stats, the position is strategic after all. But you'd expect to see the effect after a while, 6 months is longer than I would have expected, but short enough that cause and effect are undeniable.

Even so, it is a strong reminder not to rely on any one vendor for critical stuff, in case that wasn't clear enough yet.

Launching a new service every 5 minutes is obviously stretching their resources.

I wondered what happened to him?

While neither am I nor the company I work for directly impacted by this outage, I wonder how long can Cloudflare take these hits and keep apologizing for it. Truly appreciate them being transparent about it, but businesses care more about SLAs and uptime than the incident report.

Bluntly: they expended that credit a while ago. Those that can will move on. Those that can't have a real problem.

As for your last sentence:

Businesses really do care about the incident reports because they give good insight into whether they can trust the company going forward. Full transparency and a clear path to non-repetition due to process or software changes are called for. You be the judge of whether or not you think that standard has been met.

Wait till you see the drama around their horrible terraform provider update/rewrite:

It’s almost as classic as just short circuiting tests in lightly obfuscated ways.

I could be quite the kernel developer if making the test green was the only criteria.
