I am looking for this data: the top X (ten or fifteen) most visited domains (pageviews) from all devices (desktop/mobile) across all Wikipedia/Wikimedia domains. So that means across all editions of Wikipedia, Wikidata, Wikimedia, Wikisource ...
What I have tried: The closest I could find was https://wikimedia.org/api/rest_v1/#!/Pageviews_data/get_metrics_pageviews_aggregate_project_access_agent_granularity_start_end using which I can generate this data per project and then combine it across projects to get the results I want. However, it seems to be missing a few domains, like when I query for blog.wikimedia.org (or phabricator.wikimedia.org), it tells me:
The date(s) you used are valid, but we either do not have data for those date(s), or the project you asked for is not loaded yet. Please check https://wikimedia.org/api/rest_v1/?doc for more information.
Note that I am not looking for individual articles but just domains (and subdomains).
Please let me know if more information is required. Thank you your help.
