September 11 attacks

The Wikipedia article on September 11 attacks has been edited 22,407 times since it was created in 2001, by 6,689 distinct accounts and IP addresses. That works out to roughly 905 recorded changes a year — an article being rewritten in small pieces almost every hour of the day.

Within the revisions retrieved for this report, the ten busiest contributors account for about 40% of the changes, with the rest spread across a long tail of occasional editors. That is a fairly typical mix of regular maintainers and passing corrections. In the same window, about 5% of the retrieved revisions came from bot accounts, which handle routine work such as link repair and reference formatting.

Within the retrieved window, 2026 carries the most recorded activity, with 299 changes. 35 of those revisions fall in the last 90 days. The most recent recorded edit was 23 days ago.

Readership is cooling: the last three months of pageviews run about 39% below the preceding period. The clearest peak in that record falls in September 2024. Traffic spikes and editing spikes often line up, but the revision record alone cannot tell you which one caused the other, or whether an outside event drove both.

This report is built from the 500 most recent revisions retrieved from Wikipedia, about 2% of the 22,407 recorded edits. Figures drawn from that window describe the window only, and the report cannot establish why a change was made or whether it was correct.
