Created attachment 16135 [details] /wiki/ and ZeroRatedMobileAccess requests per hour for 250-99 Since 2014-07-29 ~23:00, zero tags for 250-99 look wrong: * The zero=250-99 tagged log lines declined a bit in total numbers. * The zero=250-99 tagged log lines with "/wiki/" in URL dropped by ~80%. * The zero=250-99 tagged log lines with "ZeroRatedMobileAccess" in URL increased drastically. The time of the change roughly matches I3ce7975705bd704f140a397f2233928a21ab39bd which looks relevant. Due to the "/wiki/" hits going down, the page views reported on the dashboard are jumping down too. See the attached plot of number of zero=250-99 tagged log lines per hour with "/wiki/" in URL, and with ZeroRatedMobileAccess in URL. (The short change on 2014-07-25 seems to match Ieeb940b27d75e73ce54ad0ab74ac9b72cdfbb881 and it's subsequent revert Ica00438edadc8cd06bc646ac1552c477e12dd0fa )
The graph and above numbers were computed by the /a/squid/archive/zero/zero.tsv.log-* files on stat1002.
This is per https://www.mediawiki.org/wiki/Requests_for_comment/Unified_ZERO_design#Analytics The new requests should still have X-Analytics=X-CS=250-99, even though the X-CS header will be set to "ON". If it doesn't, its a bug. Requests for ZeroRatedMobileAccess?zcmd=... should not be counted - they are resource requests to get the banner. The change I3ce7975705bd704f140a397f2233928a21ab39bd is what switched zero to the new unified model. We plan to switch the rest of zero partners to the same model.
Hi Yuri -- how was this change communicated? It seems like we were taken by surprise. thanks, -Toby

(I guess by 'X-CS' you're refering to 'zero' tags in the final X-Analytics header.) It was a vcl bug. Preliminary checks show that Yuri's above patch (comment 4, and comment 5) fixes it. I'll do more checking, when more data has been fed into the pipeline. > Requests for ZeroRatedMobileAccess?zcmd=... should not be counted - they are > resource requests to get the banner. No worries, they are not counted.
(In reply to christian from comment #6) > I'll do more checking, when more data has been fed into the pipeline. Things are back to normal. Thanks for prompt fix Yuri!
