If you tried using Claude today and got hit with errors, timeouts, or blank responses, it’s not just you.

Claude is currently experiencing a major outage. The issue was first flagged on March 2, 2026, and it appears to be affecting users across web, mobile, and API access. This isn’t a small regional hiccup or a single app glitch. It’s broad.

According to the official status updates, the first “Investigating” notice went live at 11:49 UTC. A follow-up at 12:06 UTC confirmed the team is still looking into it. No resolution time has been shared yet.

For now, users may see failed requests, inconsistent replies, or complete inability to access the service. Developers relying on Claude’s API are also reporting elevated error rates.

And yes, this is happening worldwide.

What Anthropic has officially confirmed

Anthropic has acknowledged a service disruption affecting Claude.

The status page notes “elevated errors on claude.ai.” That usually means the system is responding, but not reliably. Some requests succeed. Others fail. That explains the mix of login errors, timeouts, and half-loaded responses users are seeing.

At first, reports suggested the issue was limited to the main web interface. API access and Claude Code appeared unaffected. Later, Anthropic confirmed there were authentication issues impacting Claude Code as well.

So this isn’t just a cosmetic web glitch. It touches multiple parts of the ecosystem.

What they have not shared:

  • The root technical cause
  • Whether it’s infrastructure or deployment related
  • An ETA for full restoration

For now, the only clear message is that engineers are investigating.

Why Claude is Down?

There’s no confirmed technical explanation yet. Anyone claiming certainty right now is guessing.

Large AI systems like Claude rely on several layers working together: model servers, routing systems, authentication services, and cloud infrastructure. If one critical component fails, errors can cascade quickly.

The HTTP 500 errors users are reporting usually signal server-side failures. A 529 error often points to overloaded or unavailable backend services. That could mean traffic spikes, internal misconfiguration, or cloud-level instability. It could also be something much more mundane, like a bad deployment.

We simply don’t know yet.

What stands out is the geographic spread. Reports are coming from multiple regions, which suggests a centralized or widely shared service component is affected rather than a local network issue.

The API loophole

While the main claude.ai web interface is experiencing elevated errors, the core Claude API appears to still be operational for many users. That means developers using the API directly may still be able to send and receive requests, depending on the specific authentication flow.

If the website login is failing, you can try:

  • Accessing the Claude Developer Console (if your session is still active)
  • Using third-party platforms like Poe that integrate Claude models
  • Running existing API keys through backend integrations

In other words, Claude isn’t completely offline at the model level. The disruption appears to be hitting the web interface and certain authentication paths harder than the raw model endpoints.

That’s an important distinction.

When will Claude be back up?

Sometimes outages like this resolve within an hour. Sometimes they stretch longer if the issue involves deeper infrastructure fixes. Until Anthropic posts a “Monitoring” or “Resolved” update, users should expect intermittent failures.

If you rely on Claude for work, this is one of those moments that reminds you to have a backup plan.

Every multimodal model you've used has the same basic system. Text goes in one way, images go through a vision encoder first, audio goes through an audio encoder first, and then everything gets handed off to the language model in a form it can work with. The encoders are load-bearing and you don't just remove them.Google actually removed them.Gemma 4 12B takes raw image patches and raw audio waveforms and projects them directly into the same embedding space as text tokens. There is no vision encoder or audio encoder. One decoder handling everything.

MiniMax M3 Shows What Happens When AI Stops Thinking in Turns

Most models quit around submission 30 because they stop finding improvement and exit on their own. That's what happened when MiniMax ran a CUDA kernel optimization task against a field of frontier models. Every model except two called it done within the first 30 submissions. M3's best result came on submission 145. After 24 hours. After multiple plateaus where the numbers stopped moving and a reasonable model would have concluded there was nothing left to find. That's the thing MiniMax released yesterday. An AI model with a 1M token context window, native multimodality, and apparently a problem with knowing when to stop.

Anthropic Files for an IPO. AI Is Entering Its Public Company Era.

Anthropic has officially taken its first step toward becoming a public company. In a brief announcement on Monday, the company said it had confidentially submitted a draft S-1 registration statement to the U.S. Securities and Exchange Commission for a proposed initial public offering. The filing doesn't reveal a share price, a fundraising target, or even a timeline. For now, it simply gives Anthropic the option to go public once the SEC review process is complete. Just a few years ago, Anthropic was a small group of former OpenAI researchers trying to build an alternative vision for advanced AI. Today, it sits among the handful of companies shaping the industry's future and that's why this filing matters. It's one of the world's most influential AI labs beginning the transition from a privately funded research company to a business that may eventually answer to public shareholders. For most of the AI boom, the biggest bets were made behind closed doors. Venture firms, sovereign wealth funds, and tech giants supplied the capital while the public watched from the outside. Anthropic's filing suggests that era may be starting to change.
