Our site uses Google Tag Manager and we have China users having issues - pointing to GTM as the culprit.

I know and read that major google services are blocked in China, but does this include www.googletagmanager.com?

enter image description here

Ive read from here that Google Analytics is blocked, and read here that GA is different from GTM.

Is there a possibility that GA is blocked, while GTM is allowed? Or GTM is blocked, based on the screen shot above?

Is it possible to request from China user for a trace route maybe?

Need your insights please.


  • I am not sure what the actual truth is. The vendor (Tealium) said that they are not blocked in China and for that reason my client purchased Tealium.

According to GreatFire, Google Tag Manager is currently not blocked in China.

This doesn't mean that much though; the Chinese censors may have decided not to block GMT continuously, but only in intervals to make it seem Google is at fault.

  • yea, doesnt make sense at all, my testings are just recently and greatfire is telling that there were no blocks in the last 90 days.

Yes, it's included.

Don't use GTM in China.

Other scripts depend on GTM to properly work. If GTM is blocked, you also block lot of traffic from using other non Google-scripts integrated in GTM.

You can continue using GA (and you need to adapt), but avoid GTM in China.


yes and no, yes because the library script is still accessible, but slow, no because the entire UI is blocked in China. http://www.chinaweboptimization.com/2018/03/google-analytics-gtm-blocked-china/
