What worries me is that in Catalan Wikipedia we were expecting to beat the page views record this month with around from 18MM to 19 MM. We have a press release ready to be launched as soon as the final results of the month are known.

But if the data is not reliable we don’t dare to spread that press note even if we are sure we have beaten the record.

I also think the seemingly extraordinary increase in page views in October is most likely a glitch.

Compare this chart which shows long term trends in page (and image) requests per second.

No sudden peak in October here.

There are several steps involved in producing page view stats.

What we can say so far is the anomaly happens before or during data aggregation on our squid log post-processing server.
