Disruption activity index (0–100). Published incidents and repeated check failures carry more weight than emerging problem patterns. This is not a report count or percentage of affected users. Gaps have no observations; connecting lines do not add measurements.

Observed disruption signals combine available incidents, recorded reports, website checks, and emerging problem patterns. A low score does not guarantee that every feature is working.

Latest observation: 2026-11-08 18:11:37 UTC. Refreshes automatically while this page is visible.

How to read this calendar

Dates use New York time (America/New_York). Green means no issues observed with sufficient monitoring coverage; it does not guarantee uninterrupted uptime. Pink includes official incidents, repeated website failures, or corroborated user reports. Gray days are unknown. Activity estimates alone do not turn a day pink. Today’s result can change.

Mozilla China website uptime and response time

Website check timed out Last checked 2026-11-08 18:11:37 UTC.

Checked address: https://www.firefox.com.cn/

DNS lookup: unknown ms · TCP connection: unknown ms · TLS handshake: unknown ms. Diagnostic: ETIMEDOUT.

Unknown
Median response time

Unknown
95th percentile response time

128 failed checks; 0 restricted checks. Restricted checks are excluded from the success rate. Lines connect recorded samples across gaps; availability between checks is unknown. Response time measures receipt of HTTP headers, not full page load. Checks run from one US monitoring server and do not verify sign-in, API, or app features. These sampled results are separate from down reports and estimated activity.

Evidence behind the status

Repeated website check failures. Two recent checks of the monitored website endpoint failed. This does not establish that the full app or API is down.

Website checks and estimated activity have independent update times. Refer to each section for its latest observation.

These measurements describe different things. A reachable homepage can coexist with login or API failures. Missing evidence stays unknown.

Official component status

No mapped official components are available for this product. Parent-company status is not substituted for product status.

Official incident timeline

No product-matched incidents are available in the collected provider history. This does not prove that no incident occurred.

Recovery tracker

No recent recovery can be established from available evidence.

0 consecutive successful checks within the last 30 minutes. These checks measure the public website; they cannot establish recovery of every feature.

Slowdown detection

More successful checks are needed to establish a response-time baseline.

Recent median: unknown · Earlier median: unknown. Flags require at least 3 recent and 5 earlier checks, more than twice the baseline, and at least 500 ms extra latency. Slowness alone does not identify server load as the cause.

Emerging down-report signals

No recent emerging problem patterns are available for this service.

Emerging problem patterns can persist after an incident and do not measure report counts or prove an outage.

Is it down in your region?

Run one public website check from a community probe. Results describe that probe, not every user in a country.

Results are reused for 15 minutes. Shared free allowance: up to 60 tests per hour. A successful website check does not verify authenticated app or API functions.

Infrastructure incident context

Check whether broader platform incidents coincide with the problem you are seeing. These providers are context, not verified dependencies of Mozilla China.

About Mozilla China status on Iszdown

Beijing Mozilla Online Ltd, a.k.a. Mozilla China, is a limited company to help promote and deploy Mozilla products in China. Similar to Mozilla Corporation, Mozilla China is a for-profit company funded and created by a non-profit organization. Mozilla China was founded on March 4, 2005. It is a wholly owned subsidiary of the Mozilla Corporation. Mozilla China is co-chaired by Dr. Li Gong of Sun Engineering and Research Institute and Mr. Mingshu Li of Institute of Software, Chinese Academy of Sciences, both of whom will sit on the steering committee with Mitchell Baker, president of the Mozilla Foundation. Mozilla China built a Chinese version of the Mozilla web site, provides technical and architectural direction for Mozilla development in China, organises and operates discussion forums, and further develops Mozilla source code in China.

This page combines the available Mozilla China report activity, official product status, public website measurements, and daily history. Each measurement has its own observation time. A search spike alone does not confirm downtime, and a reachable website does not establish that sign-in or every product feature works.

No mapped official components are available for this service. Latest public website measurement: 2026-11-08T18:11:37.000Z.

What to check when Mozilla China is not working

These are troubleshooting suggestions, not a list of currently reported problems.

Mozilla China will not open

Compare your usual browser or app with a private browser window, then try another network if available. Save unsent work first. A difference between networks can help separate a local connection problem from a wider disruption.

Mozilla China is slow or only one feature fails

Record the affected action, exact error, and time. Compare the website response measurements with any official component incidents; loading a homepage does not test every feature.

Website troubleshooting guide · Sign-in problems · API errors and timeouts

Include the time, affected feature, and error message when contacting official support. Keep passwords, payment information, session cookies, and access tokens private.

Recent Mozilla China outage history

No product-matched official incidents have been archived for this service in the displayed history. This does not establish that it has never had an outage. See the daily calendar for other available evidence.

Frequently asked questions about Mozilla China

Is Mozilla China down right now?

Repeated website check failures. Two recent checks of the monitored website endpoint failed. This does not establish that the full app or API is down. This page was assembled at 2026-11-08T18:20:25.000Z.

How many Mozilla China outage reports are there today?

The displayed rolling 24-hour window contains 0 recorded reports, from 2026-11-07T18:20:00.000Z to 2026-11-08T18:20:00.000Z. This is not a calendar-day total or a count of affected people. Estimated activity is shown separately as an estimate.

Why does Mozilla China show operational when it is not working for me?

An official operational status can coexist with a local network issue, account problem, or feature-specific incident. Compare the mapped components, recent incident updates, and regional diagnostic on this page. Automated website checks test public access, not your signed-in session or every Mozilla China feature.

When was Mozilla China status last updated?

No current product status observation is available for Mozilla China. Reports, estimated activity, and website checks can provide additional context.

Has Mozilla China had outages before?

The daily calendar links available incident evidence and retains daily monitoring summaries. Pink marks service issues, green requires sufficient observations with no issues observed, and gray means insufficient coverage. The collected history is incomplete and is not a lifetime outage count or a guarantee of uninterrupted uptime.

How do I follow Mozilla China or report a problem?

Use “Watch this service” to save Mozilla China in this browser’s watchlist, then return to compare its status with other saved services. Optional browser notifications can flag status changes while the watchlist page stays open and visible; background alerts are not sent. Use the problem-report button for an outage report; contact the provider through its official website for account, billing, or private support issues. Iszdown is independent and cannot resolve provider support tickets.
