Frequently Asked Questions

We send automated HTTPS requests to websites every 60 seconds from our monitoring servers. We measure HTTP status codes, response time (time-to-first-byte), and DNS resolution. We also collect crowd-sourced reports from users experiencing issues, combining both signals to determine if a site is truly down.

Yes, Is it down checker is completely free. We monitor over 2,700 popular websites and you can check the status of any domain at no cost. No registration, account, or credit card is required to view live status, response time, uptime history, or submit outage reports. The service is funded by display advertising, which lets us keep every check, every status page, and every API endpoint open to anyone who needs them. Power users and small developers can rely on the free tier for personal monitoring; if you need enterprise SLA-backed monitoring, we recommend a paid uptime service alongside ours.

No Problems (green status) means the website is responding normally to our server checks AND user reports are at or below normal levels. There is no evidence of an outage at the time of viewing the status page. Specifically, our HTTPS probe returned a 2xx or 3xx response within the timeout window, DNS resolution succeeded, and crowd-sourced user reports are below the 3x baseline threshold for the past hour. If the site is reachable from our servers but you personally can't access it, that points to a regional, ISP, or local network issue rather than a site-wide outage.

Possible Problems (yellow status) means the website responds to our checks, but user reports have spiked to 3x or more above the normal 7-day baseline. This often indicates a partial outage, regional issue, or specific feature that is broken while the site remains technically reachable. Common causes include a CDN edge failure affecting one geographic region, an authentication or payment service partially failing, or a single feature (chat, search, video upload) breaking while the rest of the platform stays online. When a site shows yellow, scroll down to the User Reports section to see what specific issues people are reporting.

Problems Detected (red status) means either our server check confirms the site is down (HTTP error, timeout, or DNS failure), OR user reports have spiked to 5x or more above normal. This indicates a significant, widespread outage in progress. We require at least two consecutive failed server checks before flagging red — single transient failures (a brief network blip, a one-off TCP reset) won't trigger the alert, which prevents false-positive outages on otherwise healthy sites. If a site stays red for more than a few minutes, the outage is almost certainly real and affecting many users.

Our checks run from a single server region. If the website is experiencing a regional outage, CDN failure, or ISP-specific issue, it may be reachable from our servers but not from your location. Try clearing your browser cache, switching networks, or using a VPN. You can also submit a report on the site's status page to help us detect the issue.

All 2,700+ monitored websites are checked at least every hour from our automated monitoring servers. The most popular 500 sites — the ones people search outage queries for most often — are checked more frequently. Each check measures HTTP status code, response latency (time-to-first-byte), and DNS resolution. Results are stored for 24-hour historical analysis and aggregated into 24-hour, 7-day, and 30-day uptime statistics. Crowd-sourced user reports run on a separate, real-time pipeline: when you submit an outage report, it is processed immediately and counts toward the spike-detection algorithm within seconds, not the next hourly cycle.

Visit the status page for the website you're having trouble with (e.g., isitdownchecker.com/check/google.com) and scroll to the 'User Reports' section. Select the type of problem you're experiencing and optionally add a description. Your report helps us and other users identify outages.

We don't require accounts or collect personal data to use the site. When you submit an outage report, your IP address is hashed with SHA-256 and a daily rotating salt before storage — raw IPs are never saved, and the hash cannot be reversed to identify you. Hashed identifiers expire after 90 days when old reports are auto-deleted. Our first-party site analytics (Cloudflare Web Analytics) are cookie-less and aggregate only. We do display advertising via Google AdSense, which uses its own cookies for personalised ads — you can opt out of personalisation at any time via Google Ad Settings. Full details are in our privacy policy.

Uptime percentages show how much time a website was operational during a given period. For example, 99.95% uptime over 30 days means the site was only down for about 22 minutes total. We display 24-hour, 7-day, and 30-day uptime statistics based on our continuous monitoring data.

Yes — we add new websites continuously. Send the domain name to contact@isitdownchecker.com and we'll evaluate the request, add it to the catalog, and start monitoring it within a few days. Popular requests (sites people search downtime queries for frequently) are prioritised. There's no fee, no review process, and no qualification — if real users want to know whether a site is down, we want it in our index. Once added, the new site gets its own status page at /check/{domain} with response-time history and crowd-report tracking, and is included in our XML sitemap so Google indexes it too.

A public JSON API is in active development for developers and businesses who want programmatic access to monitoring data. The API will return live status, response time, uptime statistics, and recent outage events for any monitored domain, with reasonable rate limits free of charge. If you're interested in early access, contact us at contact@isitdownchecker.com — early users help us shape the endpoint design and get a higher rate-limit tier when the API goes public. In the meantime, an embeddable status badge is available — see the Embed page for HTML and Markdown snippets you can drop into a README or blog post.

Is it down checker combines automated server-side HTTPS monitoring with real-time crowd-sourced user reports using a down detector style methodology. Our 3-tier status system (No Problems, Possible Problems, Problems Detected) provides a nuanced view that catches partial and regional outages that simple ping tests miss.

If a website is down: 1) Clear your browser cache and cookies. 2) Try a different browser or device. 3) Check your internet connection. 4) Try using a VPN. 5) Wait a few minutes and try again — most outages are resolved quickly. You can monitor the site's status page on Is it down checker for real-time updates.
