Our counts of map tiles served disappeared as of 1 June 2017 (query we use). In fact, running the following simple query shows that there are no tile requests after 31 May 2017:
SELECT TO_DATE(ts) AS `date`, COUNT(1) AS requests FROM wmf.webrequest WHERE webrequest_source = 'maps' AND year = 2017 AND ( (month = 5 AND day = 31) OR (month = 6 AND day = 1) ) AND http_status = '200' AND uri_path RLIKE '^/([^/]+)/([0-9]{1,2})/(-?[0-9]+)/(-?[0-9]+)(@([0-9]\.?[0-9]?)x)?\.([a-z]+)$' AND uri_query <> '?loadtesting' GROUP BY TO_DATE(ts);
