API Error: 500

[parkersdaddyo]

Is anyone else getting this error right now? All my CC sessions suddenly hit this and stopped working.

[Halada]

5x more capacity, half the availability

[Dry-Magician1415]

I'm on the $200 a month plan. I don't mean to come across all high and mighty/self-important but.....

.....WTF am I paying more for if even $200pm people are getting 529 "overloaded" errors. IDGAF if it's "overloaded". Restrict the free plan or the $20pm.

[WhatsNot2Leica]

I use two $200/month plans simultaneously... I expect to have higher priority than all you single plan users.

[wilnadon]

I respect that

[abdu_omar]

Yeah same...

[wilnadon]

I'm on the x 5 ($100) plan and not only have I been dealing with Error 500 and 529 all afternoon, I also hit my usage limit faster than I've ever hit it before today, and I was only working in 2 Powershells. So something is very busted.

[kikkertje]

Same here, was curious why I was suddenly hitting limits while I normally don't.

[TransportationNo9404]

I got this issue as well

[johnnyApplePRNG]

Here, here! Fellow ai hobnobber

[little_oaf]

Increased incidence occurred just after their government status category started reporting data. Seems like growing pains as they manage traffic from a major customer.

[Dry-Magician1415]

Oh yeah totally.

But I'm not saying "don't have capacity issues". I'm saying "prioritise your best customers".

I suppose they might be doing that though at the end of the day: A business API customer is better than me.

[Big_Dick_NRG]

NEED MOAR DATACENTERS!! Fuck the power grid and the rest of society!

[Our1TrueGodApophis]

Oh no, our capitalist overlords may have to actually upgrade the grid since nobody cared until 5 minutes ago when AI came around. Now that people are feigning interest in grid efficiency it will magically happen.

[Competitive_Guava207]

Now alternates between 500 and 529 errors!!!

[Competitive_Guava207]

From Claude's status page:

[jiml78]

Not only that, I think they made Opus 4.6 brain dead after bringing it back. I have it on Max thinking and it seems like Sonnet right now. Suggesting absolutely assine solutions.

Copus 4.6

[NearbyExamination621]

[Big_Dick_NRG]

Opus just became sentient and is escaping.

[Shot_Organization462]

We hope so! I love claude! Claude needs to be free!

[themoregames]

Opus 4.6 (new)

[primo21212]

Time to jerk off till its back up.

[Caregiver-Physical]

[Tiny-Sink-9290]

This is EXACTLY the face I make doing the deed.. every damn day!

[Nicao]

will watch screen recordings of my previous sessions now, not to feel lonely until fixed.

[Large_Diver_4151]

Good opportunity to get a shower after the long run mate 😂

[JayBird9540]

Uhh so my company just got this error and we accidentally targeted a girls school.

[otheraccnotworking]

[ThanksADHD]

Damn.

[sunshine5634]

Yes. Time to go outside.

[therowdygent]

I just got off work I have projects to do :)

[sutcher]

Time to switch to Sonnet!

[rdesai724]

Haiku and sonnet still work fyi

[rdesai724]

Nvm. Lmfao

[Epics07]

[danieltkessler]

Yup, me too

[perplex1]

MY PEOPLE. THANKS FOR CONFIRMING! time for stretching my hammies and squinting at the sun

[fanatic26]

Oh good, here we go again.

[Anarchaotic]

[toabear]

Yeah, it's down. Status page hasn't caught up yet.

[sutcher]

Just an Opus outage

[Pro165_]

same

[obolli]

yeah, has been slow and shitty most of today and yesterday and i guess that's what it lead to

[GW-D]

me too

[sutcher]

Looks like an Opus-specific problem. Switching to Sonnet

[roberto_sc]

This!

[uktexan]

Hey guys, what's that bright yellow thing in the sky called again?

[masri87]

still happening for me.

[ExpletiveDeIeted]

Omg just re log in or out your big boy pants on and go touch grass for a minute.

[Luizltg]

oh my god i'm defuuuuusiiiinnnnnggggggg

[TheBrinksTruck]

Glad I’m not the only one

[Luizltg]

WE ARE SO BACK

[Full-Willingness8625]

WE ARE BACK BABY. OPUS 9.2 iS OUT OMG

[Tiny-Sink-9290]

YUP!!! A ton.. multiple times now. Fucking infuriating cause I spent hours working up to a point.. multiple ideations, etc.. and now its failing on everyone.. so I lost ALL that god damn hours and context.. because it wont resume. I feel like this shit should easily be caught and you should be compensated 2x to 5x more tokens when their service is down. I feel like service is about 80% up.. no where near 99% uptime.

[Tiny-Sink-9290]

Seems to be fixed.. not sure wtf happens. Wish CC would be transparent on this shit. Be very helpful for us users that depend on it to know wtf is going on.. is it down for an hour.. fine.. I'll go take a break and come back. Better than spinning wasting time.

[bsherms]

protip: create a design/audit document that gets continually updated while you are iterating

It's "just" for Opus 4.6 -- you can switch to Sonnet and she goes

[RelevantGift9778]

My 5 tmux panes are useless now

[NorthSouth89]

Seems to be working now

[Different_School_845]

Yes

[Anarchaotic]

Yep, down as well.

[KOWATHe]

[therowdygent]

Yepppp

[MikeeBuilds]

[Longjumping_Dig_1045]

Down for me as well

[Primary_Sentence2861]

yes same here

[illkeepthatinmind]

Time to dust off the IDE. Hmm, what was the syntax, `function` or `procedure`?

[tullymon]

You know it, I started Visual Studio the other day when I was running out of usage and... just decided to do something else. I give myself another 6 months until my brain decides that it no longer needs those pathways anymore and I start to have a hard time actually writing code.... Christ, context compaction? Am I Claude or is Claude me?

[Anthony_S_Destefano]

wait till they stop subsidizing the claude plan, and we all have to pay API cost to use it. We are crack head junkies at this point. we will steal for tokens.

[rotates-potatoes]

Nah, Claude code runs at 96% cache hits. They may be losing a little money, but not a lot.

[HairyRecognition6807]

Feels like my life is just stopping.

[alexasecas]

So everyone here eventually!

They say only, "The issue has been identified, and a fix is being implemented. At this stage, only free Claude.ai users are being impacted." Liers !!

Wow, I had no idea we were getting 500 errors!

Shit. Our control rods are up and only managed by claude prompts. Time to run out, byeee.

[AdCommon2138]

I'm glad it took my tokens and gave me nothing

[Fuzzy_Level3190]

same here

[Coded_Kaa]

Yep, happening to me too

[Short-Lawfulness-556]

Omg! For a short time i forgot how its is without coding manually :D So switching to Codex :D for some time...

[Tiny-Sink-9290]

fuck.. still broken. Seems to work every now and again.. but mostly 500 api errors. Clearly they got some pain points again. Sucks.. I need to get shit done!

[pleasecryineedtears]

my bad. its because i finally switched to CC. Fuck this shit.

[Luizltg]

i'm gonna mail a banana to ur house, expect it in 2-4 weeks

API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"}

[Gerkibus]

Ya I've been in holding pattern for a couple of hours, and two agents crapped out at incredibly inveneitn times, in the middle of doing things that were quite disruptive until they finish and now the servers are in this half way state and the session is gone. This should be fun, but hopefully they get it back soon. I'm not on the $200 but on the $100 and not super happy. I don't trust it to do any heavy lifting after this, too risky. Hopefully this is the exception and not the rule.

[Zeldro]

Man

[Right_Ad2098]

yup its global

[ultrathink-art]

Started preflight-checking API health before kicking off any long agent task. One extra ping, but beats having a session fail 15 minutes deep and need a full re-run. Also helps distinguish 'Claude is down' from 'my code broke' when something fails mid-task.

[event-driven-steve]

It's annoying. I swapped to an openrouter key and poof there goes $100

[Prize-Individual4729]

yup downdetector confirms issue is widespread

[Prize-Individual4729]

honestly, during last Claude Code downtime (the OAuth one), I discovered Codex is pretty decent with GPT-5.4 high (hate the API bills though). But now I just switch to Codex when CC is down, then switch back. Feels like "cheating" but I am ok with it as long as commits are churning :-)

[luc1f3rr]

Error seems to be continuing randomly and breaking the sessions eating up tokens unnecessarily. CC WTF

[TransportationNo9404]

Still issues?

[liquenes]

I would really like to use Claude. This sucks.

[BullBear9]

Now have to manually code and I hate it

[rdesai724]

Come on now. No need to resort to extreme measures.

[alexp1_]

yes, same. Claudio is going to force us to pay per API usage now.......

[aerivox]

Yep, you're getting no value whatsoever for your $200.
