"Unusual traffic from your computer network"
You might see "Our systems have detected unusual traffic from your computer network" if it seems like a computer or phone on your network is sending automated traffic to Google.
What Google considers automated traffic
- Sending searches from a robot, computer program, automated service, or search scraper
- Using software that sends searches to Google to see how a website or webpage ranks on Google
What to do when you see this message
The error page most likely shows a CAPTCHA (a squiggly word with a box below it). To continue using Google, type the squiggly word into the box. It's how we know you're a human, not a robot. After you type the CAPTCHA correctly, the message will go away and you can use Google again.
Common issuesI don't see a CAPTCHA
If you don't see a CAPTCHA, try these steps in order:
- Check for malware on your computer. Malware is malicious software that can be installed on your computer without your knowledge. Some malware can cause Google to show this message. Learn how to detect and remove malware.
- Contact your network administrator. If you share a Wi-Fi network with others, like at a school or business, another computer in your network might be sending automated searches to Google. Your network administrator or IT professional might be able to locate and stop the source of the problem.
- Reset your modem or router. If you don't have a network administrator, try resetting your modem or router to see if that fixes the issue.
Once the automated searches have stopped, you should be able to search normally on Google.
Google Search blocks IPs, IP ranges, and in some cases, whole ISPs, when a large percent of the traffic entering our networks is abusive.
If the blocking started within the past few weeks, it is likely to be related to the use of the "Hola VPN" browser plugin, or a program for Mac/Win/Android/iOS. The best thing to do is to uninstall the Hola VPN from your computer or network.
If you are an Internet Service Provider (ISP), explain to your users why it is important for them to uninstall this type of VPN. When the abuse hitting our network stops, we automatically stop blocking the IP(s)/ISP(s) that were sending the bad traffic. Learn more about Hola VPNs here.
Unfortunately, sometimes non-Hola traffic gets looped in with the abusive traffic. We are working on a way to change our protections so that we'll only block Hola traffic in the future.
