This is independent monitoring from our server (one location, a probe of DeepSeek’s API gateway about every five minutes, 414 probes in the last 24 hours). It can differ from DeepSeek’s own status page, and it cannot see problems limited to other networks or to your account. For DeepSeek’s own announcements, open the official DeepSeek status page.
The panel above is a live check of whether DeepSeek is reachable right now, measured from our own server about every five minutes. It refreshes itself every minute, so there is no need to reload the page.
DeepSeek incident log, last 30 days
Built automatically from the same probe data. We count an incident when three or more probes in a row fail; the log shows when it started, when the first successful probe ended it, and how long it lasted. Short blips of one or two failed probes are not listed.
No incidents in the last 30 days: our server never recorded three failed probes in a row.
What to do if DeepSeek is not working
If the panel above says DeepSeek is up but it fails for you, the cause is usually local: a browser extension, a VPN or DNS problem, an outdated app, an account issue, or an API key, balance or rate-limit error. If the panel shows problems, wait a few minutes before changing anything, and do not resend the same request in a loop. The step-by-step fixes for the web chat, the app, login and API error codes are in our DeepSeek not working troubleshooting guide.
Our chat is separate
The browser chat on Chat-Deep.ai does not use DeepSeek’s consumer web chat. It sends requests to the DeepSeek API from our own server, so it may keep working when the official chat or app is busy or down, and it can be down when they are fine. If the official chat is unavailable, you can try the free DeepSeek chat on this site; it needs no account.
Official DeepSeek incidents and endpoint checks
Check whether DeepSeek is down right now. This page combines DeepSeek's official status information with independent reachability checks for Web Chat and the API gateway.
No widespread DeepSeek outage detected
No. DeepSeek is not currently reporting a widespread outage.
The official status is operational, and both the Web Chat edge and API gateway answered our independent checks.
Independent-site disclosure: Chat-Deep.ai does not operate DeepSeek and is not affiliated with DeepSeek. Official reports are identified separately from our own server-side checks.
Three separate signals
Live DeepSeek Status by Service
DeepSeek's official status is the primary source for declared incidents; independent reachability checks are displayed separately.
Official incident status
Official DeepSeek status data (REST)Operational
- Active incidents
- 0
- Tracked components

First-party measurements
DeepSeek Reachability History
Our monitor records one server-side Web Chat and API gateway reachability check approximately every five minutes. Data starts when this plugin is activated.
Web Chat reachability
- 24 hours 100.00% 415 valid checks Coverage: 287 of about 288 five-minute intervals recorded (99.7%).
- 7 days 100.00% 2160 valid checks Coverage: 1992 of about 2016 five-minute intervals recorded (98.8%).
- 30 days 100.00% 8940 valid checks Coverage: 8440 of about 8640 five-minute intervals recorded (97.7%).
- 90 days 100.00% 18695 valid checks Partial sample: 15205 of about 17191 five-minute intervals recorded (88.4%). Missing intervals are not counted as successes or failures.
API gateway reachability
- 24 hours 100.00% 415 valid checks Coverage: 287 of about 288 five-minute intervals recorded (99.7%).
- 7 days 100.00% 2160 valid checks Coverage: 1992 of about 2016 five-minute intervals recorded (98.8%).
- 30 days 100.00% 8940 valid checks Coverage: 8440 of about 8640 five-minute intervals recorded (97.7%).
- 90 days 100.00% 18695 valid checks Partial sample: 15205 of about 17191 five-minute intervals recorded (88.4%). Missing intervals are not counted as successes or failures.
Uptime is calculated among valid recorded checks only. Coverage compares distinct five-minute intervals with the approximate schedule; missing intervals are not counted as a success or a failure. These measurements come from the Chat-Deep.ai server and are not DeepSeek's SLA.
What the current DeepSeek verdict means
No. DeepSeek is not currently reporting a widespread outage. The official status is operational, and both the Web Chat edge and API gateway answered our independent checks.
A green result does not guarantee that every DeepSeek feature works for every user. Account problems, regional routing, browser extensions, local DNS, an expired API key, insufficient API balance, or request-level rate limits can affect you while the global service remains operational.
Down for everyone or just you?
How to Tell a DeepSeek Outage from a Local Issue
Use the symptom and the first diagnostic response to separate a service outage from a local, account or request problem.
| Symptom | More likely explanation | First check |
|---|---|---|
| “Server is busy” or very slow replies | Capacity pressure or intermittent degradation | Refresh this page, wait briefly, then try a shorter new conversation. |
| Login loop or blank chat | Cookies, browser extensions, account session or regional route | Try a private window and the same official sign-in method. |
| API HTTP 401 | Missing or invalid API key | Check the Authorization header and key source. |
| API HTTP 402 | Insufficient API balance | Check billing and balance in the official platform. |
| API HTTP 429 | Concurrency or request-rate pressure | Reduce parallel requests and retry with backoff. |
| API HTTP 500 or 503 | Potential server error or overload | Check the API component and retry safely. |
| Works on mobile but not desktop | Browser, DNS, firewall or network-specific issue | Try another browser and network before assuming a global outage. |
For deeper steps, use the DeepSeek not working troubleshooting guide. Developers should also consult our DeepSeek API error codes and API rate-limit guide.
Transparent, reproducible checks
How Our DeepSeek Status Checker Works
Methodology last reviewed August 21, 2026.
Official status
The checker reads DeepSeek's current official status data server-side, including active changes, the published component list, component uptime and incident history. It reads the status provider's REST transport first and validates DeepSeek's page ID and custom domain, then uses a bounded, non-executing parser for embedded Next RSC page data only when REST data is incomplete. Official-source responses are cached for up to two minutes; a clearly marked last-successful snapshot may be used for no more than 30 minutes during a source failure.
Web reachability
Our server requests the official Web Chat endpoint. A response confirms edge reachability only; it does not test your login, chat history or successful generation.
API reachability
Our server requests the official models route without a key. An expected HTTP 401 proves that the API gateway answered, but it does not test authenticated model inference.
Conservative verdict
Independent failures never override an official incident state. Timeouts, bot protection and source-format failures produce “unable to verify” or “possible access issue,” not a false global outage claim.
Limitations
- Checks run from one server location and cannot prove availability in every country, ISP or corporate network.
- The unauthenticated probes do not test account login, billing, file uploads or a complete model response.
- The component list follows DeepSeek's published status data dynamically, aliases only improve labels and order. If both REST and the bounded page-data fallback change format, this page shows an unknown state instead of guessing.
- No visitor IP address, browser fingerprint, DeepSeek credential or API key is collected by this checker.

Frequently asked questions
DeepSeek Status FAQ
Is DeepSeek down right now?
Use the live result at the top of this page. It compares DeepSeek's official incident state with separate Web Chat and API gateway reachability checks. Always use the displayed last-check time because availability can change quickly.
Is DeepSeek down for everyone or just me?
If DeepSeek fails across multiple devices and networks while an official incident or multiple independent failures are shown above, a wider outage is likely. If it works in another browser, device or network, the problem is probably local or account-specific.
What is the official DeepSeek status page?
DeepSeek publishes official service information at status.deepseek.com, including API, Chat, model-mode, search, vision, upload, maintenance, uptime and incident details.
Why does DeepSeek say “server busy” when the status is operational?
A server-busy message can be intermittent, regional, account-specific or limited to certain requests. Wait briefly, try a new conversation and compare another device or network before concluding that DeepSeek is down for everyone.
Is the DeepSeek API down?
Review the API components and the independent API gateway check above. HTTP 401, 402 or 429 normally points to authentication, balance or concurrency rather than a global outage. Repeated 500 or 503 responses are more consistent with a service-side problem.
Can DeepSeek be unavailable in only one country or region?
Yes. Routing failures, ISP problems, local restrictions or regional infrastructure can affect some users while global monitoring remains operational. A regional failure should not be described as a worldwide outage without supporting evidence.
How often is this DeepSeek status page updated?
The public status snapshot and official-source cache refresh approximately every two minutes, and scheduled independent history checks run approximately every five minutes. During an official-source failure, a last-successful official snapshot can remain visible for up to 30 minutes and is explicitly marked stale. The visible “Last checked” timestamp is the authoritative freshness indicator.
Is Chat-Deep.ai the official DeepSeek status service?
No. Chat-Deep.ai is an independent resource and is not affiliated with or operated by DeepSeek. Official information and independent measurements are labeled separately.
While DeepSeek is down: protect your work
- Do not repeat the request in a loop. Repeated requests can add load and create duplicate work. Follow the service guidance and use bounded retries.
- Copy your prompt out before refreshing. Unsent text is frequently lost when a session is re-established.
- If the chat is unavailable, check the API separately. An API-based application may still work, but gateway reachability alone does not establish this. Only a successful authorized request confirms completion for that model, account, and moment; do not expose an API key in browser code.
- Follow the official incident updates. If no recovery time is given, wait before checking again. Do not assume a particular outage duration from this page.
How this page checks DeepSeek status
This page combines two sources. The first is DeepSeek’s official incident information, which is authoritative for confirmed outages but only updates once DeepSeek has acknowledged an issue. The second is our own independent reachability checks against the public web chat and the API gateway, which provide a separate observation of whether an endpoint responded. They do not establish successful model generation or diagnose the cause of a failure.
Neither source is perfect on its own. A connection problem on your side can look like an outage here, and a partial incident affecting one region may not appear in either. Chat-Deep.ai is an independent resource and is not operated by, endorsed by, or affiliated with DeepSeek.
For the measurement definitions and available evidence, see our DeepSeek reliability methodology and data coverage. Check the stated observation window and coverage before interpreting any figure; the methodology is not proof that multi-region measurements have been collected.
What has happened with DeepSeek recently?
Not every report of DeepSeek “not working” is an outage. Several platform changes landed between late July and mid-September 2026, and some of them produce errors that look exactly like downtime. Check this list before assuming the service is down.
| Date | What changed | Why it can look like an outage |
|---|---|---|
| 24 July 2026 | The legacy model names deepseek-chat and deepseek-reasoner were discontinued, three months after the notice published on 24 April 2026. | Any integration still calling those names fails while the web app works normally. |
| 31 July 2026 | DeepSeek-V4-Flash entered public beta on the API as deepseek-v4-flash. | Apps pinned to the older preview name can error until they are updated. |
| 13 August 2026 | DeepSeek-V4-Pro reached general availability across the app, web and API as deepseek-v4-pro, with three thinking levels (low, high, max) and native support for the Responses API format. | Response shapes and mode names changed, which can break strict client parsing. |
| 16 August 2026 | New API pricing took effect, using a peak and off-peak structure in which off-peak requests are charged at half price. | A billing change, not an availability change. |
| 21 August 2026 | DeepSeek-V4-Flash-Vision-Exp was released as deepseek-v4-flash-vision-exp. | An experimental model can behave inconsistently without the platform being down. |
| 10 September 2026 | DeepSeek-V4.1-Flash was released as deepseek-flash with native image input and lower prices. The earlier V4 Flash models were retired; their legacy names are temporarily routed to V4.1-Flash. DeepSeek kept the V4 Pro API service running after 14 September with billing unchanged. | Answers, image-token counts and costs can change for code that still sends a retired name, even though requests keep returning HTTP 200. |

How often has DeepSeek actually been down?
DeepSeek publishes per-service uptime on its own status page. The table below preserves the August 2026 figures recorded from that page on 29 August 2026. It is a historical snapshot taken before the month ended, not a final full-month availability report:
| Service | August uptime shown on 29 August 2026 |
|---|---|
| DeepSeek V4 Pro API | 99.92% |
| DeepSeek V4 Flash API | 99.81% |
| DeepSeek-V4-Flash-Vision-Exp API | 100.00% |
| Chat service | 99.84% |
| Instant mode | 99.79% |
| Expert mode | 99.76% |
| Vision mode | 100.00% |
| File upload service | 100.00% |
| Search service | 99.84% |
Read those figures alongside the live check at the top of this page. The table preserves the historical figures shown on 29 August; the check above reports its own latest observation time. Neither predicts the outcome of your next request. Source: status.deepseek.com.
