Request of tfl.gov.uk webserver logs

The request was partially successful.

Dear Transport for London,

I would like you to provide me with the access logs for the webserver for the following websites http://www.tfl.gov.uk, and also http://journeyplanner.tfl.gov.uk.

I am referring to the file normally called "access_log" or similar that Apache (the web server software used by your website) creates. Such files usually contain one line per
access made to the website. An example is as follows:

127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET /apache_pb.gif HTTP/1.0" 200 2326 "http://www.example.com/start.html" "Mozilla/4.08 [en] (Win98; I ;Nav)"

Regarding the above files, I am interested in the last 1 month, or more if file size is not too large.

If you summarise these files on a regular basis (monthly,
quarterly, or whatever) to produce graphs or tables of "hits per day", "hits per month", or similar, then I would like copies of such summaries for both websites also.

Regarding the summary, I am interested in the last 1 year.

In summary I am looking for:

a) accesslogs for webserver of the last 1 month traffic for website http://www.tfl.gov.uk

b) accesslogs for webserver of the last 1 month traffic for website http://journeyplanner.tfl.gov.uk

c) any summary report created for the last 1 year for website http://www.tfl.gov.uk

d) any summary report created for the last 1 year for website http://journeyplanner.tfl.gov.uk

Yours faithfully,

Mr. B M Tyers

Dear Mr Tyers

 

TfL Ref:  FOI-1584-1112

 

Thank you for your email received by Transport for London (TfL) on 6
February 2012 asking for webserver access logs.

 

Your request has been considered under the requirements of the Freedom of
Information Act 2000 and TfL’s information access policy. I can confirm
that TfL does hold the information you require.  You asked:

 

I would like you to provide me with the access logs for the webserver for
the following websites http://www.tfl.gov.uk, and also
http://journeyplanner.tfl.gov.uk.

    

I am referring to the file normally called "access_log" or similar that
Apache (the web server software used by your website) creates. Such files
usually contain one line per access made to the website. An example is as
follows:

    

127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET /apache_pb.gif
HTTP/1.0" 200 2326 [1]http://www.example.com/start.html "Mozilla/4.08 [en]
(Win98; I ;Nav)"

    

Regarding the above files, I am interested in the last 1 month, or more if
file size is not too large. If you summarise these files on a regular
basis (monthly, quarterly, or whatever) to produce graphs or tables of
"hits per day", "hits per month", or similar, then I would like copies of
such summaries for both websites also.

 

Regarding the summary, I am interested in the last 1 year. In summary I am
looking for:

    

a) accesslogs for webserver of the last 1 month traffic for website
http://www.tfl.gov.uk

    

b) accesslogs for webserver of the last 1 month traffic for website
http://journeyplanner.tfl.gov.uk

    

c) any summary report created for the last 1 year for website
http://www.tfl.gov.uk

    

d) any summary report created for the last 1 year for website
http://journeyplanner.tfl.gov.uk

 

TfL is not obliged to supply some of this information as it is subject to
a statutory exemption to the right of access to information under section
40(2) of the FOI Act.

 

In this instance the exemption has been applied as the information you
require includes IP addresses, which are personal data associated with
individuals’ online browsing history.  This information could be used in
conjunction with other data to build a comprehensive picture of an
individual’s wider browsing habits. Additionally enquires made on TfL’s
websites would be available in significant volume, representing the
personal data and habits of our customers.  Disclosure of this personal
data would be a breach of the DPA, specifically the first principle of the
DPA which requires all processing of personal data to be fair and lawful.
It would not be fair to disclose this personal information when the
individuals have no expectation it would be disclosed and TfL has not
satisfied one of the conditions of Schedule 2 of the Data Protection Act
which would make the processing ‘lawful’.

 

This exemption to the right of access to information is an absolute
exemption and not subject to an assessment of whether the public interest
favours use of the exemption.

 

However, we can provide the following information regarding our online
traffic:

 

a) accesslogs for webserver of the last 1 month traffic for website

month (January 2012) as follows; 40,101,231 page views,  5,688,834 visits,

d) any summary report created for the last 1 year for website
[5]http://journeyplanner.tfl.gov.uk.
