Site owners from multiple countries, including Taiwan and various European regions, report identical patterns of data loss beginning November 13:
“Taiwan is experiencing the same issue. On 11/13, there was a sudden drop in traffic, and from 11/14 to 11/17, it decreased by 20-30% compared to the same period last month.”
People note that while their real-time analytics show expected traffic levels, historical data since November 13 reflects only about half of their actual visitor numbers:
“I usually track the data from the day before yesterday on the current day. However, there’s only nearly 50% traffic on my website. Just want to know is there anyone with the same situation as me?”
Why This Matters
This disruption poses challenges for organizations relying on GA4 for business intelligence and reporting.
Many companies face difficulties in performance analysis and decision-making processes without accurate historical data.
Despite numerous support threads and community discussions, Google hasn’t officially addressed the situation or indicated whether the missing data will be retroactively restored to affected accounts.
We will continue to monitor this situation and provide updates as information becomes available.
