Think of it like one big distributed system. OpenAI is down, so people migrate to Claude, now this one gets overloaded and goes down, etc.

So not a coincidence, one went down first and users migrated causing further DOS. At least that's my guess.

It'd be funny if this is true because that'd prolly mean nobody is touching Gemini even as a fallback.

Or that Gemini is built to handle massive load spikes, and/or has a ton of excess capacity

Nope. I am getting Gemini errors now...

They probably broke something on purpose so that they are not left out.

Now I'm just imagining a shared datacenter with Anthropic/Google/OpenAI/SpaceXAI all in the same room and everyone but Google is yelling about things being down, Google looks over at their racks of servers and discretely uses their foot to unplug their section and say "Awww darn! We're down too!".

The shilling in this cascade of comments is unbearably cringe, make it stop

It could also mean that Google can absorb essentially unlimited demand spikes by load shedding.

Lol I didn't even think about Gemini missing from the list. Not sure what that says about Gemini or me :)

Gemini was just waiting for everyone else to go down before remembering it had an outage feature too.

Just now I got this from gemini

It looks like there's no response available for this search. Try asking something else.

I bet they had to implement that manually to make it look like they failed too!

I did, for stuff i do in cursor.

i also finally installed opencode and switched its model to muse 1.3

both are decent.

Google stopped putting so much money into SOTA models. All the hype has migrated. I was also frankly turned off when I got a popup from Gemein said I would either have to pay or have my conversations used for training. This may have always been true for other providers but when I declined, Gemini stopped remembering my conversations and that definitely made me move out.

Gemini said that?

Gemini is what I mostly use (good enough, basically free - or massively generous free limits, and to me Google as a company is a LOT less objectionable than all the US-based alternatives), but I don't recall it ever saying that.

OTOH, my basic assumption online is that there is no privacy, and free AI in exchange for acknowledged lack of privacy seems fair enough.

Gemini 3.8 which just came out sounds like it's very good and a great deal though.

Someone noted Gemini was also having issues in another thread.

Not even the best agent that starts with a G

I find it hard to believe that enough people would flock to from Claude and Chat to Grok to cause an outage. I feel like Gemini is the dominant release valve in this case especially for enterprise.

Don't forget that there are a ton of tools out there that will automatically fall back in case of outage

E.g. say you chose Sol as your default in Cursor, but Opus is your 2nd choice, it's going to give up on Sol after a few tries and switch to Opus

Or you have copilot code reviews set up, and it falls back

Etc

Yep. Too many of us are still thinking that humans are the actors behind a lot of internet behaviors when automated systems/bots/scripts have been causing issues on conventional internet systems for years.

With AI it's even easier to trigger problems like you say. Capacity is so constrained by compute that outages are common. Because outages are common people/AI develop failover systems in their harness. When a big system has issues, suddenly everyone has issues.

It's almost an expected emergent behavior.

It’s cursor’s model so plausible, lots of folks use cursor still.

Compared with ChatGPT, those services have a minuscule amount of users. It shouldn’t be surprising that a ChatGPT outage causes Claude and others to go down.

If everyone has the same "Use X or else Y or else Z" cascading list... That reminds me of "The Power of Two Choices in Randomized Load Balancing" (1991) [0] paper, where writeups and visualizations occasionally get posted to HN.

In short, you can get pretty good outcomes for a low cost by picking 2 random alternates, then going with whatever one measures as healthier.

Is this speculation or is there a reason you believe this?

Especially considering memory/gpu/compute are scarce so these services are likely running with very little buffer.

Any GPU that isn't running at 100% is a wasted GPU.

Edit: Updated per valleyer's suggestion.

"Domino effect" would probably be the more relevant named phenomenon there.

This isn’t a thundering herd problem, it’s a cascading failure. (Thundering herd is about a bunch of workers waking up simultaneously)
