Notable: Added "Microsoft Azure, which provides cloud infrastructure for all Anthropic products (Worldwide)."

Hopefully it goes better for them than it has for GitHub.
dylan604•Mar 26, 2026
hope in one hand and do something in the other to see which one fills up faster. hoping is always a strained good idea, but hoping on Azure really strains credulity
copperx•Mar 27, 2026
But increases credibility?
seemaze•Mar 27, 2026
If you hope for a hand full of do, you win(doze?)
varispeed•Mar 26, 2026
Ahh now it is clear why so many outages lately. Solid choice.
victor106•Mar 27, 2026
When you host a solid model on terrible infrastructure, the infrastructure wins
baq•Mar 27, 2026
As God intended.

I fear the day it becomes the other way around.

Microsoft 365 Copilot has enabled Claude models, and I imagine they want that running on Azure?
jadbox•Mar 26, 2026
Likely. MS doesn't like using models that are not hosted by them internally (see VSCode Copilot)
rvz•Mar 26, 2026
There you go. So when Azure has an outage, so will Anthropic (and Github).

Now expect both of them to have unstable uptime and outages every week.

brookst•Mar 27, 2026
You don’t thino Anthropic has any kind of resiliency, so net new compute reduces downtime? Any docs on that view?
CodeCompost•Mar 27, 2026
That is significant for us. We have already accepted the risk of using Microsoft Azure so we use GitHub Copilot for that reason.

We have Claude disabled at the moment but if Anthropic has moved over to Azure then we can consider to start using it.

"Accepted the risk", just in case people don't know, is a compliancy term. I don't mean that Azure is risky.

speedgoose•Mar 27, 2026
> I don't mean that Azure is risky.

Depending on the company and their sector, people will nod in approval, or start laughing.

My company also accepted the risk of using Microsoft. We have a "data sharing agreement" together, with very powerful magical words. Compliance people are happy and sleep well.

They added Microsoft but alongside them also list Google and Amazon for "all products".

Title: Welcome to the Anthropic Trust Center

.. was this a deep link? You might want to repeat in the comments

Works for me, gotta scroll down a bit

gnabgib•Mar 26, 2026
That's an h3 not a title. Looks like they probably meant: https://trust.anthropic.com/updates, it's still an entry in an h3 (with "Welcome to the Anthropic Trust Center" as the title), but it is at least the most recent update (canonical would stop this being directly linked)
octoberfranklin•Mar 26, 2026
WTF is a "subprocessor"?

They should just be honest and say "data loophole".

pdabbadabba•Mar 26, 2026
It is an important legal concept under the GDPR and other data governance frameworks.
dchuk•Mar 27, 2026
It’s basically another party that is used as infrastructure by the company you’re using the services of, who has access to your data, but that sub processor doesn’t need to extend its terms down into the eula. So like if you host databases on aws, they are your sub processor.
craxyfrog•Mar 27, 2026
Worth noting the distinction between subprocessors that handle customer data vs. those that handle operational/business data. The ones in the "Customer Data" category are where the compliance implications are most significant for enterprise customers under GDPR, HIPAA, or similar frameworks.

For anyone evaluating this for a procurement decision: the relevant questions are (1) which subprocessors have access to content you send in API requests, (2) what data processing agreements are in place with each, and (3) what is the notification window for new subprocessor additions. The 30-day notice for customer data subprocessors is fairly standard for enterprise SaaS at this point.

Publishing this list proactively rather than only on request is a positive signal, even if the list itself is fairly short.

With respect to my private data, it seems all roads eventually lead to California.
crefiz•Mar 27, 2026
Sorry, what does that means? GDPR national here
alsetmusic•Mar 27, 2026
Probably a reference to Silicon Valley?
asawfofor•Mar 27, 2026
so i thought there were multiple fedramp service providers offering hosted claude models. not sure why they are linking to one in particular
dan000892•Mar 27, 2026
Where are they linking to just one? The chart shows three: Palantir, AWS GovCloud, and GCP w/FR-High Assured Workload.

The chart should show ITAR also IMO. Only Palantir and AWS GovCloud would have checkboxes and that’s extremely relevant to defense contractors. (Vertex AI is available within an FR-High assured workload but not ITAR, the only conceivable reason for which would be foreign person access to the US sovereign production environment.)

yalogin•Mar 27, 2026
I don’t know what I am looking at there. What is a subprocessor?
stingraycharles•Mar 27, 2026
It’s a legal term for handling data. It’s when Anthropic uses an external party to handle their data / systems, but Anthropic is the legal entity responsible for the data privacy, as the customer (you) has a contract with Anthropic.
zvqcMMV6Zcr•Mar 27, 2026
https://www.gdprsummary.com/gdpr-definitions/sub-processor/ in context of GDPR/DORA it is about formalized agreements with 3rd parties that will handle data, your own and of your clients.
ctmnt•Mar 27, 2026
To be clear, for those reading these comments and thinking “oh no Azure”, this is an addition to the list of cloud companies that provide “cloud infrastructure worldwide” for “all products”. Alongside GCP and AWS. This is not a GitHub style announcement that they’ve moved all operations to Azure.
kleene_op•Mar 27, 2026
Coincidently, Claude Code appears to be down right now (in Europe West at least).

Everytime I hear of something X Azure announcement, that something just seem to break right away.

I know correlation is not causation, but my opinion of Azure is already too damn low to not link those two events.

matheusmoreira•Mar 27, 2026
It's also down for me here in Brazil. Getting overloaded errors for about one hour now. It's been happening a lot this week. Is this normal for Anthropic?
SomeUserName432•Mar 27, 2026
Working fine for me right now, from Brazil. Claude via Github Copilot at least.
matheusmoreira•Mar 27, 2026
I'm using Claude Code on the terminal. Not sure if it matters.

  API Error: 529
  {
    "type": "error",
    "error": {
      "type": "overloaded_error",
      "message": "Overloaded. https://docs.claude.com/en/api/errors"
    },
    "request_id": "..."
  }
The promotional double usage period is just about to end too. Sucks.
CamouflagedKiwi•Mar 27, 2026
It's down for me too. A colleague says it's up though - it's possible they're shedding different groups of users (he has the Max subscription, I don't).
louiereederson•Mar 27, 2026
They announced a $30b+ commitment with Azure back in November, so not really a surprise that Azure is now listed as one of their cloud providers. https://www.anthropic.com/news/microsoft-nvidia-anthropic-an...
