Wikimedia Traffic Analysis Report - Google requestsMonthly requests or daily averages, for period: 1 Aug 2012 - 31 Aug 2012 (last 12 months) |
See also: Requests by destination or by origin / Methods / Scripts / User agents / Skins / Crawlers / Op.Sys. / Mobile devices / Browsers / Google / Country data / Traffic trends, and notes about reliability of these data
This report shows all requests to Wikimedia servers where a Google server of service was involved in any way, be it the GoogleBot crawler or FeedFetcher collector scripts that run on Google servers, or a user that follows a link from a Google Web or Google Desktop search results page, or from Google Maps or Google Earth etcetera. Technically speaking three fields in the squid log records are checked for this: client ip address, referer header and user agent header. A request can originate from an ip address which has been registered by Google and/or it can carry a referer tag that tells us a user clicked a link on a Google results page and/or it can carry an agent string that mentions a Google application which can reasonably be assumed to be genuinely Google's. See bottom of page for further details. In total Google was somehow involved in 45.2% of daily external page* requests Google referred to our sites, through its services including search, maps, and Google Earth, 183,019,140 page views per day, representing 38.7% of our external page requests. Including all of its different search crawlers and services hosted on its servers, Google itself requested another 30,753,800 page pages per day, representing 6.5% of our external page requests. * = mime type text/html only | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

IP ranges: known ip ranges for Google are 64.233.[160.0-191.255], 66.249.[64.0-95.255], 66.102.[0.0-15.255], 72.14.[192.0-255.255], Agents: as for genuine agent strings: too many crawlers indentify themselves as 'GoogleBot' to take this at face value. They are accepted as genuine Google crawler requests only when the ip address matches a known range (see above). Other records that mention GoogleBot are counted as GoogleBot? (question mark, as this may include partners, like DoCoMo). However when the agent string mentions Google Desktop or Google Earth this is always accepted Service: the service name is based on the agent string (plus for GoogleBot check for ip address, see above), if this is inconclusive it is based on the referer string. Here is detailed breakdown per service of indicators that pointed to Google (total ≥ 3)
Top Level Domain 'undefined': requests with top level domain 'undefined' are nearly all requests from anonymous ip addresses (crawler and other services) Note: averages below 1 are always rounded up to 1 |
Errata: WMF traffic logging service suffered from server capacity problems in Aug/Sep/Oct 2011. From mid September till late November squid log records for mobile traffic were in invalid format. In a an unrelated server outage precisely half of traffic to WMF mobile sites was not counted from Oct 16 - Nov 29 (one of two load-balanced servers did not report traffic).

Absolute traffic counts for October 2011 are approximatly 7% too low.
Data loss only occurred during peak hours. It therefore may have had somewhat different impact for traffic from different parts of the world.
and may have also skewed relative figures like share of traffic per browser or operating system.
Data could be repaired for logs from mid October onwards. Older logs were no longer available.
WMF has since improved server monitoring, so that similar outages should be detected and fixed much faster from now on.
