On 2013-12-17 the total of zero=470-01 tagged requests jumped from <10K requests/day to ~550K requests/day on 2013-12-18. Is this sane traffic increase, or did something break?
The maximum was reached on 2013-12-19 with ~820K requests/day. The number is declining again, and back to ~300K requests/day for 2013-12-22. It seems this spike can be attributed to Grameenphone announcing Wikipedia Zero on their homepage: http://www.grameenphone.com/whats-new/wikipedia-zero-knowledge-free (And judgding by the requested URLs below, Wikipedia Zero has been added to Speed Dial as well) The increase was >98% on the zero.wikipedia.org bn.zero.wikipedia.org domains. bn is in the carrier's showLangs, and the carrier only zero-rates the zerodot domain. Which matches the above explanation. The following three URLs are the most requested for each day since 2013-12-19: http://bn.zero.wikipedia.org/wiki/Main_Page http://zero.wikipedia.org/?cs=operamini_grameenphone_speeddial http://bn.zero.wikipedia.org/wiki/%E0%A6%89%E0%A6%87%E0%A6%95%E0%A6%BF%E0%A6%AA%E0%A6%BF%E0%A6%A1%E0%A6%BF%E0%A6%AF%E0%A6%BC%E0%A6%BE:%E0%A6%A8%E0%A6%BF%E0%A6%B0%E0%A7%8D%E0%A6%AC%E0%A6%BE%E0%A6%9A%E0%A6%BF%E0%A6%A4_%E0%A6%A8%E0%A6%BF%E0%A6%AC%E0%A6%A8%E0%A7%8D%E0%A6%A7 (According to google translate, the last item is “Selected Articles” on the “Wikipedia” namespace) Those three URLs account for about a third up to half of the zero=470-01 tagged traffic per day since 2013-12-19. The URLs are requested at least an order of magnitude less. About half of the zero=470-01 tagged traffic had “-” as referrer. About 1/6 had http://bn.zero.wikipedia.org/wiki/Main_Page . That matches what we saw before the announcement. The Grameenphone's announce listed zero.wikipedia.com (“.com” instead of “.org”) as address, so we saw some requests to that domain. But that was <1% per day for the zero=470-01 tagged traffic. I did not notice other peculiarities in the traffic. So it seems to be good traffic that is caused by the carrier's advertising.
