For the [[ https://superset.wikimedia.org/superset/explore/p/gD4ny7GXpLG/ | past 3 months ]] we have been noticing a rise in unique devices. In July we had 1.8B unique devices, a +19% YoY increase.
The increases are noticeable in certain regions and countries. for ex. in July ESEAP increased 23% YoY, driven by large increases in Singapore (+330%) and Hong Kong(+220%). We suspect that the increase in unique devices may be linked to a rise in VPN usage in the countries where we're observing these trends.
We want to investigate further to find out if this is indeed caused by VPNs or due to some other reason.
Conversely pageviews have been dropping YoY which can be attributed to our work to [[ https://phabricator.wikimedia.org/T364126 | disable ]] classes of automated traffic originating from Google [[ https://developer.chrome.com/blog/private-prefetch-proxy | Chrome ]]. These declines are in line with our expectations.
