VPN triggering unusual traffic message on Google pages

  • I just started using VPN & have hit a Google problem. Sometimes it works fine, but a lot of times Google responds to searches via VPN as if they are robot generated. Instead of search results, I get this msg:

    "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot."

    There's a CAPTCHA to proceed, but it doesn't necessarily work.

    Google Help says VPNs can cause the problem:

    "Some VPNs send traffic that violates the law or websites' terms of service. If you're an Internet Service Provider (ISP), explain to your users why they should uninstall these VPNs. When the abuse to Google's network stops, we automatically stop blocking the IP(s)/ISP(s) that were sending the bad traffic."

    The problem doesn't always happen. Maybe it's triggered when the volume of traffic from Opera's VPN reaches a certain level. It goes away if VPN is turned off.

    Are other people having this problem? Apparently it's done at the ISP / IP level. Is Opera likely to change the VPN to comply with Google's standards?

  • I work for an IT company. We google stuff a lot. Even we get crap from google about unusual traffic because of the volume of weird searches. It is probably a similar issue.

  • There is nothing to be done about it. We hit that page a lot while we are not even using Google frequently, and from our company’s IP address in Europe.

    It is not surprising to see it while using a public VPN since you are sharing a single IP address with many users.

  • Apparently it's done at the ISP / IP level.

    Why would you think so?

    Per your description, it seems to me it's Google trying to come to terms with itself regarding its data collecting etc.
    Though it looks like a security feature - at first sight. For example, a mail service sends a user such a prompt when s/he enters with VPN after previous entries without.
    Looking like a security feature: you're in, say, Moscow, next day you're in Amsterdam? Security definitely implied cause you're protected from unauthorised breeches.

    I get blocked when I do google searches with VPN turned on (not mail). It only happens at certain times of day. The block message is

    Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot.

    There's a link to a Google Help page. I was talking about the Google Help statement I quoted earlier in the OP (see below). Maybe I misunderstood, but I thought it was saying that they block in response to ISP & IP traffic ... I assumed they meant some VPN ISPs & IPs have traffic patterns that trigger something in Google's robot detecting software. You can find it at this link. At the bottom of the article is a "Common issues" section with this dropdown: "I shouldn't be getting blocked". It says:

    Some VPNs send traffic that violates the law or websites' terms of service. If you're an Internet Service Provider (ISP), explain to your users why they should uninstall these VPNs. When the abuse to Google's network stops, we automatically stop blocking the IP(s)/ISP(s) that were sending the bad traffic.

    Do you have a different interpretation?

  • Why would you think so?

    Basically the problem happens because Google detects several requests to their servers coming from the same IP address, what causes their security system to block that IP thinking that it's an attack.

  • @aimzz There is nothing to be done about it, mate.

    It was an OCD moment-- I hate being misunderstood 🐱

    Ah!

    If you call it different, IP means your IP to the server/service, or the IP used by the VPN to connect you; ISP means your ISP - or the ISP allowing for such traffic. (Both former and latter are the same respectively.)

    Thanks! 🆙 My knowledge about VPN is pretty limited.

    Overall it seems that Google & the VPN are at stalemate on the blocking issue.

  • Using a VPN and using Google is counter productive. The VPN is for enhanced privacy. If you don't want people tracking you, don't use Google.
