Anthropic reports: All systems operational (“All Systems Operational”)

from Anthropic's own status page, checked Aug 31, 2026, 8:54 PM UTC
Our probes and Anthropic's own status page agree: both show Anthropic as reachable right now.

Anthropic's own component breakdown, as they publish it

  • claude.aiOperational
  • Claude Console (platform.claude.com)Operational
  • Claude API (api.anthropic.com)Operational
  • Claude CodeOperational
  • Claude CoworkOperational
  • Claude for GovernmentOperational

These are Anthropic's components, named and scored by Anthropic. We do not map them onto the functions we check above, because we have no way to know which of their components our checks touch. Two lists, side by side, neither one rewriting the other.

This is Anthropic's own claim about their service, shown separately from what we measured. We never change our own numbers based on what a vendor reports, and this reading never changes theirs. Read both.

Is it Anthropic, or is it you?

Watching an outage above does not tell you whether your own connection or site is also having a problem. Enter your own URL for one live check, right now, no signup. This checks the site you enter, not Anthropic -- it cannot diagnose Anthropic's own systems.

What we measured, function by function

Anthropic answers on more than one surface, and they can fail apart. Each row is one surface, checked from the same regions. The verdict above follows the auth row, because that is the surface we treat as this service's own; a failure on any other row is a partial outage, not a full one.

No account needed, and we never store your IP address. Reports are counted separately from our own measurements and are always shown as unverified.

These are unverified reports from people using Anthropic, counted separately from what our own probes measure. Anyone can file one, no account is needed, and the region on a report is chosen by the person filing it. We never open, extend or close an outage in our record based on report volume: only our own measurements do that. We started counting reports for Anthropic on August 28, 2026.

measured entries are our own probes' readings; declared entries are the vendor's. How this check works

We have been measuring Anthropic since August 20, 2026. We show nothing from before that date, and we never add an outage we did not observe ourselves, from any source.

Need this in writing? Generate an SLA evidence report for Anthropic covering any window you pick, with our measurements and Anthropic's own claim at the time, side by side.

Monitor your own site the same way

This page shows what we see when we check this service, using the same ten regions, for a site you run. RealUptime Monitor watches your own servers from inside your network, and it starts free.

Tell me when this goes down

Get told when we measure this

We will tell you when our probes stop reaching Anthropic, and again when they can reach it again. That is our own measurement from ten regions, not Anthropic's status page. No account, no card.

Delivery channel

Double opt-in: nothing is sent until you click the link in the confirmation email. One email when a measured outage opens, one when it closes, and a one-click unsubscribe in every one. We do not send anything else to this address.

Anthropic uptime measured by RealUptimeLive, from this page's own readings.

The badge shows the share of our probes that succeeded over the last 30 days, and the window is printed on it so the number always says what period it covers. If our readings go stale it says stale, and if we have no readings it says so: it will not show green on data we cannot vouch for. Free, no account, and it links back here. See how the badge works for every window and the honesty rules behind it.

What Anthropic's SLA implies, from our measurement

At or above your target

We measured none of downtime for Anthropic over the 285h 40m since we started watching it on 2026-08-20, which is 100% uptime by our reading. A 99.9% target allows 17 minutes over that period.

By our measurement there is no shortfall to claim for this period.

This is computed from our own probe measurements, not from Anthropic's SLA instrumentation. Their contract is normally measured against their own systems, with their own exclusions and a claim window, so their figure and ours will differ. Use this to start the conversation and ask for their number. It is not legal advice and it is not a determination of what you are owed.

secondaryfunctional: live API
https://api.anthropic.com/v1/chat/completions
RealUptime is not affiliated with Anthropic; the name identifies what we measured, and nothing here speaks for Anthropic's own team. We send a single web request to Anthropic from 4 regions on our own schedule and time the response. We do not see inside Anthropic's systems, do not use an account or real transaction, and are not the same signal Anthropic's own team has access to. Treat this as one external data point, not a verdict. At least one endpoint we check for Anthropic is a real functional API call (marked “functional” above), not just a landing page, so a clean read there is a stronger signal than reachability alone, though it still does not cover every feature of the service. Anthropic operates in a limited set of regions, so we only check it from where it is actually available; we do not probe from a region we know it does not serve. We started monitoring this service on August 20, 2026 (11 of 14 days so far, 46676 of 500 checks). We show a full track record once we have enough continuous history. Check back soon, or monitor your own site continuously with RealUptime. Read the full methodology.
