  • The number of distinct IP addresses accessing the website
  • “ Named users” – distinct, registered users that have logged in at least once during the month. Peak in named users in March 2003 occurs prior to the opening up of most areas of the website to open access i.e. not requiring login. This was carried out Autumn 2003. “ Visits/month” – a “visit” is one or more accesses to the website from a single IP address with no break of more than 30 minutes between accesses.
  • Indexing of the site by local search engines (Google, Exalead) produced considerable distortion of the stats from May 08 onwards. This plot shows monthly hits (NOT pages, as have previously been preferred) with local search engine activity removed.
  • The steep rise in pages served in Sep 07 is in large part driven by 83k pages accessed during first use of our local Google indexing software. Number of pages served in May 2008 distorted by indexing of the site by Google (at least 1.1 million hits of 2.7 million hits) and Exalead (655985 hits), with a consequent distortion of the gigabytes served (43.5 Gb ascribed to Exalead against some 3Gb for Google out of 76.2Gb total) Ditto June 2008. Google hits >1.3 million hits, Exalead > 1 million hits. Note distinction between hits and pages – pages used in these stats but no mathematical relationship between the two, other than hits>pages. Local googling pages subsumed within overall Manchester site number of 1.47 million July 2008. Local Google > 0.93 million hits. Exalead not apparent. August 2008. Local Google > 0.70 million hits. Exalead not apparent. September 2008. Local Google > 0.36 million hits. Exalead not apparent. October 2008. Local Google > 0.31 million hits.
  • Values are averages over the most recent six months of reliable statistics The ABPA figure include the value for “allergic bronchopulmonary aspergillosis”
  • “ Countries” includes entries for Commercial, Network, Unresolved/Unknown, Old style Arpanet, Non-profit Organisation, Information. After the UK, page accesses are dominated by these generic categories, and individual country figures appear low as a result. Only the top 20 countries are visible in the stats. After the UK and generic categories, the dozen or so other countries hold no surprises, with the developed nations taking most of the places.
  • Shows the effect of update emails in 2006 (July, Sep, Nov, Dec), 2007 (Feb, Apr, Jun, Sep, Nov, Dec) and monthly updates thereafter, maxima generally occurring on the day of the update issue. No update for October 06 in the archive but a pronounced, one day surge occurred, akin to the update effect. Peak on May 1 st 07 following April 30 th update. Figures for May 2008 and subsequent months distorted by local search engine (Google, Exalead) indexing of the site.
  • May 2010. Total of 84389 pages for A fumigatus, of which 79448 attributable to one IP address, (Wanadoo), using PageNest. PageNest is a browser which will allow the download of an entire website. Jan 2011. CADRE moved to new server mid-month
