That's because Claude is on a lunch break and decided to take a short breather.
phishin•1h ago
Bro deserves it.
rikthevik•1h ago
I think we all deserve a little break right now.
sebastiennight•58m ago
I'm experimenting with a simple ritual: if Claude is out, I'm out.

I'll just go for a walk outside.

And I don't mean "if I can't access Claude to do my work", I mean, just in general - I'll just ping claude.ai from time to time and use Claude's breaks as a break reminder.

Why should AI get a breather and not us?

session usage limits this week feel like ass. Even when being careful to not break prefix caching.
headcanon•55m ago
I've been seeing much higher session limits late at night (US time). Workday usage struggles though.

I'm looking into how to structure my work to run some autonomous-safe jobs overnight to take advantage of it.

And here I thought April would be the month they could hit the mythical two 9's of uptime
sebastiennight•57m ago
They hit 9, twice, does it count?
grogenaut•28m ago
soon their goal will be to hit A 9, like 89

More than by the downtime I am much more surprised by the actual uptime. Hard to imagine how difficult this must be, given the speed of growth.

Can you speak a little more to this? I'm curious what kind of parameters one must consider/monitor and what kind of novel things could go wrong.
aleksiy123•8m ago
My guesses are:

hardware capacity constraints is going to be the big one

Effective caching is another, I bet if you start hitting cold caches the whole things going to degrade rapidly.

The ground is probably shifting pretty rapidly.

Power users are trying to get the most out of their subscriptions and so are hammering you as fast as they possibly can.

Harnesses are evolving pretty rapidly, as well as new alternatives harnesses

Makes the load patterns less predictable.

The demand is probably increasing faster than they can adapt.

Users are pretty sensitive to model quality changes. You probably want smart routing, but users want the best model all the time.

Models keep getting bigger and bigger.

lostlogin•37m ago
But… imagine that same scientific research but you have an unlimited budget. I’d imagine that helps.

Some of the comments here mention their monthly spend, and it’s eye watering.

On the other hand, the status page is blaming the authentication system, which one would think is not a frontier-class problem.

Imustaskforhelp•52m ago
just tried it, can confirm claude.ai is down.

So there was a recent article that I read which said that claude is now trading at a trillion dollars (yes with a T) evaluation in private markets.

We are definitely creating corporations and people which depend on AI companies themselves and the reliability of these tools is certainly a question worth asking. I am seeing quite many downtimes in products like github and claude being shown on Hackernews multiple times.

Is there a life cycle of enshittenification of such products which grow too valuable? What are (are there?) some practical lessons for such scalability that these trillion dollar companies are missing or is it just a dose of reality that such massive corporations can't compete with downtime with even my 7$/yr vps?

My question is, Is this an engineering roadblock with its limits in reality for or a management/entreprise roadblock for low downtime?

plodman•52m ago
Literally just got an email about connecting GitHub to the iOS app and now it’s down. Spike in traffic perhaps?
152334H•52m ago
why does this even occur? if it's merely compute limitations, why not just 429 some requests?
ryanisnan•50m ago
Have you run a system in production? There are a multitude of reasons that a system can go down. There's no indication so far from Anthropic that this was merely compute limitations.
consumer451•46m ago
Yeah, this is not just inference. First thing for me was an MCP I use went down in Claude Code, models still worked. Now "API Error: 529 Authentication service is temporarily unavailable."
lionkor•43m ago
Its most likely a "You're totally right, this fix broke production! Let me fix it"
KronisLV•39m ago
> There are a multitude of reasons that a system can go down.

Start doing post mortems then!

At the very least, them using any off the shelf service that's shitting the bed would inform others to stay away from it - like an IAM solution, or maybe a particular DB in a specific configuration backing whatever they've written, or a given architecture for a given scale.

Right now it's completely like a black box that sometimes goes down and we don't get much information about why it's so much less stable than other options (hey, if they just came out and said "We're growing 10x faster than we anticipated and system X, Y and Z are not architected for that." that'd also be useful signal).

Or, who knows, maybe it's just bad deploys - seems like it's back for me and claude.ai UI looks a bit different hmmm.

MavisBacon•52m ago
Glad I started using the desktop app which is still working. Gotta say though, all of these difficulties with Claude are making me nervous as I use it a lot for work and really don't like ChatGPT/OpenAI for functional and personal reasons. Zo Computer has been my main fallback when Claude is failing, I'll use one of their many models temporarily within Zo's interface.
threepts•49m ago
A trillion dollar valuation.

They should ask Codex now that Claude Code is down.

You're absolutely right! AI could be very helpful in this situation!

Oh no wait... the outage is with out AI itself, so how can AI help? Allow me to re-evaluate.

Fublutenuating...

Yes, let's ask AI!

Oh no wait... the outage is with AI itself, I already correctly identified this above.

Bubbluating...

It seems you will have to rely on your engineering skills to solve this problem yourself, ie, you're cooked! I will auto-renew your subscription to ensure you can be sure you'll have access to AI to solve this problem if it ever comes back online.

SimianSci•45m ago
The spend at my organization has reached beyond the $200,000 per month level on Anthropic's enterprise tier. The amount of outages we have had over these past few months are astounding and coupled with their horrendous support it has our executive team furious.

its alot of money to be spending for a single 9 of reliablility.

deadbabe•39m ago
We are spending the equivalent of 32 monthly software engineer salaries on Claude per month.

SimianSci•7m ago
Our expense is roughly around 12.3 software developers when you break it down across all people related expenses. But we've spent alot of time and energy prior to this focusing on our ability to measure our software development output across multiple teams. The delivery improvements are not evenly applied across all teams, but the increases that we have seen suggest a better ROI than if we had hired 12 developers.
cactusplant7374•39m ago

shimman•23m ago
GitHub, along with MSFT in general, have massive copilot mandates where workers are being shamed into using slop tools to fix serious on-going issues. GitHub seems wholly incapable of resolving their issues: money isn't a problem, talent isn't a problem, but business leadership is definitely a major problem.

Look at how other companies are suffering massive outages due to LLMs too like AWS and Cloudflare. Two companies that use to be the best in the industry at uptime but have suddenly faltered quite quickly.

Companies that have even worse standards will quickly realize how problematic these tools are. Hopefully before a recession because this industry seems to be allergic to profitable businesses and leaders that have been around since ZIRP have shown zero intelligence in navigating these times.

argee•13m ago
> talent isn't a problem

Is that true? Microsoft pays significantly below other FAANG salary bands, it’d be a bit shocking if this has zero impact on their talent pool.

They also have one of the worst recruiting pipelines known to man, which to be fair is a business leadership issue.

bayarearefugee•38m ago
> has our executive team furious

And yet they will continue to spend wheelbarrows full of money with Anthropic because they want so badly to reach the point where they can fire you.

SimianSci•19m ago
I think there is alot of baseless fury behind your words, but my regular interactions with my leadership dont lead me to think they have the end goal of replacing labor. We're blessed to have leadership with technical backgrounds, so the tools are regarded more as significant intelligence enhancers of already exceptionally smart engineers, rather than replacements.

Doesnt seem to us to be wheelbarrows of money, when you consider the average AWS/Azure bill.

walrus01•38m ago
Five nines? No, nine fives
Someone1234•34m ago
Obviously there is only so much you can say; but is that $200K due to the raw number of seats you have, or are you burning through a lot on raw API usage? I guess I'm trying to understand, large business, or large usage.
SimianSci•27m ago
we are in the SMB space, the spend is almost entirely usage for us at this point, rather than seat cost. For context, we are a software firm focused on difficult engineering problems, but I cant divulge much else.

jtfrench•40m ago
If this can happen to Anthropic, imagine all the companies building on top of Claude Code for live products. Hopefully the industry is learning that competent problem solving human engineers are still very much needed when you have increasingly deceptive non-deterministic genies running your production stack.

All it took for Codex to resume a stalled Claude Code session:

> I'm working with Claude Code on session aaaaaaaa-bbbb-1223-3445-abcdefabcdef which I'd like to hand-off to you, do you know how to read the session, my input and Claude's output so we can resume where I left off?

gpt-5.5, medium effort. "Resumed" session fully in under 2 minutes. Outages like today's are so common that I've now got the time to re-evaluate Codex every other day.

hubraumhugo•33m ago
It's rare in history that a software product can be so unreliable without any negative business impact because it's the category leader and demand only keeps growing.

Reminds me of the early days of World of Warcraft, when servers went down frequently because Blizzard couldn't keep up with all the load. Everyone was frustrated but of course nobody stopped playing.

melon_tusk•32m ago
What are good alternatives?
nzoschke•31m ago
Hug ops to everyone involved in these outages and trying to maintain uptime.

But glad my team is staying nimble and has multi-model (Anthropic, Codex, Gemini), multi-modal (desktop, CLI/TUI, web) dev tooling.

As our actual coding skills collectively atrophy, we'll either need to switch tools or go for a walk when the LLM is down.

In the cloud era I advised against a multi-cloud strategy, as the effort to impact just wasn't there. But perhaps this is different in the LLM era, where the cost of switching is pretty darn low.

justrunitlocal•27m ago
Or maybe these ops people should realize that these companies intend to make their jobs toast and just abandon ship to still very well paying jobs at more respectable corps.
justrunitlocal•31m ago
We've been running our 10 dev org on 8 H100s on open models (with some tweaks). Sure they aren't as good as the big providers but they 1. don't go down 2. have pretty damn high tok/s. It pays for itself.

Posting with a fresh account because I'm not supposed to share these details for obvious reason. If you want help on setting this up, just reply with a way to reach you.

ok_dad•28m ago
yea just buy 300k worth of hardware and bob's your uncle
justrunitlocal•26m ago
It was pretty hard to justify the purchase to the board but we got a decent deal from a nearby data-center (~15% discount). Thankfully, it's fixed cost, its an asset we can use for our taxes, and it will survive for years to come. The only thing we have to work on is maintenance as well as looking into some renewable energy options.

We're also looking into how to do some secure cost sharing with this so that all people need to pay for are what it costs for us to run everything! We're just planning on reserving at least 51% of the capacity for us and the rest for everyone else.

ok_dad•12m ago

> We are continuing to work to resolve the issues preventing users from accessing Claude.ai, and causing elevated authentication errors for requests to the API and Claude Code.

What are you doing with the authentication servers? This isn't the first downtime I've seen caused by that.

MycroftJones•24m ago
And claude is back up.
andyjohnson0•24m ago
They can't fix it because the thing that they need to fix it is the thing that doesn't work. /s

But seriously: while I don't use Claude, this issue of perceived unreliability seems to be approaching the point of existential risk for Anthropic. Whats the theory about why they're struggling? Compute capacity? Load? Lack of focus on SRE?

Put it another way: is their downtime due to something fundamental about serving inference, or just bad engineering choices? Given their resources, it seems astonishing.

bborud•21m ago
I have been keeping an eye on the outages. This is why I am looking more deeply into what I can do with self-hosted models. When I see people who want to build products on top of these services I can't help but think that people are mad. We're still a long way from these services being anywhere near stable enough for use in a product you'd want to sell someone.
AtNightWeCode•19m ago
The uptime with Claude is poor. I use it for workflows more or less 24/7. It is often unreliable. Fine, it is cheap. What I really dislike is the uneven quality of the service. Clearly it does NOT work as stated. Opus 4.7 sometimes give ancient code back. Just the other day it even stated that the latest version of Opus was 4.5 and 4.x something for ChatGPT.
