'Our Systems Have Detected Unusual Traffic From Your Computer Network': What It Means and How to Fix It

A Google page that says “Our systems have detected unusual traffic from your computer network” means Google thinks your searches come from a program. Solve the “I’m not a robot” check and you can keep searching.

If the page keeps coming back, something on your network is still sending automated searches. The steps below help you find it and make it stop.

What “unusual traffic from your computer network” means

The message means Google saw searches from your IP address that look automated. An IP address is the number that identifies your internet connection to every site you visit.

Google cannot see who sits behind an IP address. It only sees the pattern of requests. When searches arrive too fast, or in the way programs tend to search, Google pauses that address and asks for proof that a person is there.

Google’s own help page calls this automated traffic. Its list includes robots, computer programs, search scrapers, and software that checks where a site ranks on Google. Website owners deal with the same problem from the other side, which they call bot traffic.

The block page usually shows three things:

• The message, with a short note that the page checks whether a person or a robot is sending the searches.
• A reCAPTCHA box, the “I’m not a robot” check. Sometimes picture puzzles follow.
• Your IP address, the time, and the address you tried to open.

Write down the IP address and the time. You will need them if you ask an IT team or your internet provider for help.

Why Google shows it: five common causes

Often you did nothing wrong. The searches that set off the check can come from someone or something that shares your connection.

1. Someone else on your network

Schools, offices, hotels, and cafés put many devices behind one public IP address. If one laptop on that network runs a program that searches Google, everyone on the network can get the check.

Mobile networks and some home internet providers do the same thing at a larger scale. Many customers share one address. Google lists both shared networks and other users of the same internet provider as causes.

2. A VPN or proxy

A VPN sends your traffic through another company’s server. Thousands of users can share the same VPN exit address. If a few of them run bots, Google flags the address, and you get the check too.

Apple’s iCloud Private Relay works in a similar way for Safari. It hides your IP address behind a relay. Apple says some websites may then ask for extra steps before you can sign in or see content.

3. A browser extension

Google’s page does not name extensions. Still, some extensions send searches in the background. SEO toolbars that check rankings are one example, and Google’s list of automated traffic includes rank-checking software. Auto-refresh and page-monitor extensions can also send the same request over and over.

4. A script or tool sending searches

If you, or someone in your home or office, runs a program that searches Google, this is the cause. Rank trackers, scraping scripts, and some research tools all count. If that is you, skip to the developer section below.

5. Malware

Malware is harmful software that runs on a device without the owner’s consent. Some of it sends searches or clicks ads in the background. Google lists malware on your computer, or on another computer on the same network, as a cause.

How to fix the unusual traffic error, step by step

Work through these in order. Stop as soon as the message goes away.

1. Solve the reCAPTCHA. Tick the box and finish any picture puzzle. Google says this clears the message. If no check appears, make sure JavaScript is turned on.
2. Turn off your VPN or proxy. Search again. If the message stops, the VPN address was the problem. Pick a different server or contact the VPN company.
3. Turn off iCloud Private Relay for a moment if you use Safari on an iPhone, iPad, or Mac. Then search again.
4. Test your extensions. Open a private or incognito window. Most browsers turn extensions off there by default. If searches work in that window, turn your extensions off one at a time in a normal window to find the culprit.
5. Scan for malware. Run the security tool built into your system, such as Windows Security on a PC. Remove anything it finds. Do the same on other computers on your network if you can.
6. Switch networks to test. Turn off Wi-Fi on your phone and search on mobile data. If the message shows on one network only, the cause is on that network.
7. Restart your router. Some home connections get a new IP address after a restart. It does not always work, but it costs nothing to try.
8. Ask for help. On a school or work network, tell the IT team and give them the IP address and time from the block page. At home, contact your internet provider. Google suggests both.

How long does the unusual traffic message last?

Google does not publish a time limit. Solving the check lets you keep searching. If the message returns again and again, the source of the traffic is still active.

The message stops when that source stops. That is why fixing the cause is the only lasting fix. Clearing cookies or switching browsers will not help if the address itself keeps sending automated searches.

Is the unusual traffic message a scam?

The real message appears on a google.com address and asks you to tick a box or pick pictures. That is all it asks for.

Be careful if a page with this message asks you to download a file, call a phone number, or paste a command into your computer. Google’s check never does that. Microsoft’s security team has written about fake captcha pages, called ClickFix, that trick people into running a pasted command. Close the tab.

Why your script gets the unusual traffic page (for developers)

If you wrote code that searches Google, this page is what it gets back. A script sends many searches from one IP address, often with no cookies and the same timing every time. Google spots that pattern fast. Your code then gets an HTTP 429 “too many requests” error or a redirect to a google.com/sorry/ page with a captcha.

Google’s spam policies call this machine-generated traffic. They name “scraping results for rank-checking purposes” as an example. Doing it without express permission breaks Google’s Terms of Service.

Our guide to scraping Google search results with Python shows what a plain script gets back from Google. It also explains why a homemade scraper needs proxies, a real browser, and constant fixes.

Google’s own Custom Search JSON API is not the way out either. It is closed to new customers, and existing users must move off it by January 1, 2027. We cover the details in the Custom Search API shutdown guide.

The simple fix is to stop sending searches from your own machine. A Google SERP API fetches the results page for you and returns it as JSON. The provider handles blocks and retries, so your code only sees finished results. Serplify’s SERP API, for example, charges $0.005 per successful page and nothing for blocked attempts (checked October 2026).

If you only need a few manual searches with filters, Google’s search operators work fine in a normal browser. Just search at a human pace.
