Is Claude Down? How to Check and Confirm a Real Outage

When Claude suddenly stops responding, freezes on a blank reply, or throws an error, the first question is always the same: is Claude down for everyone, or is something broken on my side? Sorting that out takes about sixty seconds. Below, you will learn to answer is Claude down in about a minute, and to tell a real outage apart from a problem you can fix yourself. This guide walks you through it step by step so you stop guessing, avoid needless troubleshooting, and know exactly what to do next.

The fastest way to tell if Claude is down

Your single most reliable check is the official status page. Anthropic publishes real-time service health on its status page, and the same page also answers at the address status.claude.com. It lists each part of the platform separately — the Claude web app, the Claude API, Claude Code, and Claude Cowork — so you can see exactly which piece is affected instead of guessing.

Here is how to read it:

• All systems operational (green): Anthropic sees no problem. If you still cannot use Claude, the fault is probably on your end — keep reading.
• An active incident (yellow or red): Claude is down or degraded for everyone. There is nothing to fix on your side; Anthropic is already working on it.
• Scheduled maintenance: a planned window where some features may be briefly unavailable.

The status page also shows a timeline of past incidents, so if you land on it mid-outage you can watch updates roll in as engineers investigate, identify, and resolve the problem. That live commentary is the difference between anxiously refreshing the app and calmly knowing when service should return.

One tip: look at the specific component that matches how you use Claude. The web chat can be perfectly healthy while the API is degraded, or vice versa. If you build with the API and only that line is red, then "is Claude down" has a very precise answer — yes, but only for developers, not for people using the app in a browser. In short, the cleanest response to is Claude down always comes from this page first.

Common symptoms when Claude is down

A real outage tends to look consistent and widespread. If Claude is down at the platform level, you will usually see one or more of these:

• Every message fails, not just one — new chats and old chats alike.
• Pages load slowly or time out before Claude even starts to reply.
• Login fails, or you get bounced back to the sign-in screen repeatedly.
• Responses start and then stop halfway, or come back completely blank.
• Voice mode, file uploads, or Claude Code all break at the same time.
• You see server-side error codes rather than a polite "try again" nudge.

Error messages are a strong clue about whether Claude is down or something smaller is wrong. A Claude internal server error or a can't reach Claude error points toward a server-side or connection problem. The Claude overloaded error usually means the service is up but swamped with traffic — a partial, temporary condition rather than a full outage. And if Claude cuts you off mid-answer only occasionally, that is far more likely a limit or a single glitchy request than a platform-wide failure.

Is Claude down, or is it just you?

Before you assume the worst, rule out your own setup. Most "outages" people report are actually local hiccups. Use this table to read the symptom and point yourself in the right direction.

If the right-hand column keeps lighting up, run this quick local checklist before deciding Claude is down:

1. Try a different network. Switch from Wi-Fi to mobile data (or the reverse). If Claude works on one and not the other, your network or a firewall is the culprit — not Anthropic.
2. Open a private or incognito window. This bypasses cached files and browser extensions. Ad blockers and privacy tools sometimes break the chat interface entirely.
3. Try another browser or the mobile app. If Chrome fails but Safari works, the problem is your browser profile, not the service.
4. Sign out and back in. A stale session token can make it look like Claude is down when your account simply needs to reauthenticate.
5. Clear the cache or hard-refresh with Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac).
6. Check your account status. If you have hit a message cap or your plan lapsed, Claude will refuse work in a way that mimics an outage.

If Claude loads but behaves oddly — weird formatting, missing buttons, half-loaded pages — that is often a client-side issue rather than a true outage, and our guide on Claude not working walks through those fixes in detail.

Third-party outage trackers: a useful second opinion

The official status page is the source of truth, but it is not the only signal. Sometimes users notice a problem before Anthropic posts an incident, and independent trackers can confirm you are not alone. Sites like Downdetector, StatusGator, and IsDown aggregate user reports and show spikes in complaints in near real time.

Use them as a second opinion, not a verdict. A sudden surge of reports on Downdetector while the official page still reads green is a strong hint that an incident is brewing and simply has not been posted yet. Conversely, a flat report graph while you are seeing errors is a good sign the problem is yours to fix.

Social feeds help too. A quick search for "is Claude down" on X or Reddit will surface a wave of posts within minutes if there is a genuine outage. When dozens of strangers are reporting the same blank-reply behavior you are seeing, you can stop troubleshooting your own machine and just wait it out.

What to do while Claude is down

Once you have confirmed Claude is down for everyone, the smartest move is to stop fighting it. Nothing on your end will help. Here is how to make the wait productive instead of frustrating:

• Save your work. Copy any long prompt or draft you were mid-way through into a notes app so a refresh does not lose it.
• Subscribe to updates. On the status page you can request email or SMS alerts for the affected component, so you learn the moment service is restored without hammering refresh.
• Retry gently. When the status page flips back to green, give it a few minutes. Recovering systems sometimes throw a lingering overloaded error while traffic rebalances.
• Have a fallback ready. If a deadline depends on Claude, keep a backup workflow or an alternate model in mind so an outage never fully blocks you.
• Do not change your settings in a panic. Deleting your account, reinstalling, or rotating API keys during a real outage fixes nothing and can create new headaches once service returns.

For developers, an outage is a good reminder to build resilience into your integrations: sensible timeouts, exponential backoff on retries, and graceful error messages so your own users are not left staring at a spinner. If you need the human touch — a billing question, a suspected account issue, or an incident that drags on far longer than the status page suggests — Anthropic's help center is the right place to search for guidance or open a ticket.

The bottom line

Answering "is Claude down" is a two-step reflex once you know the drill. First, open the official status page and read the component you actually use. Second, if the page is green but you still have trouble, run the local checklist — different network, incognito window, another browser, fresh login. Nine times out of ten that pair of steps tells you exactly where the problem lives and what to do about it, without any wasted effort. Claude currently spans models like Opus 5, Sonnet 4.6, and Haiku 4.5, and because the status page reports each component separately, this two-step check takes under 60 seconds no matter which one you use. That is the whole method for answering is Claude down with confidence.

Third-party trackers are a fast first read — but know their limits: Claude on Downdetector explains why it flags false alarms and misses the API entirely.
