Request For Information - Ref. No. FOI17798


Thank you for your email of 24 November 2017, requesting information from Ordnance Survey in accordance with the Freedom of Information Act (FOIA) 2000:

I am looking for information about internet web pages accessed by staff. Please could you provide me with the following:

  1. A list of the 500 most accessed websites – in terms of page views (or however you record this) on computers over the past 12 months (December 2016 to December 2017).
  2. Please could you provide the URL of the website and number of times it has been accessed by computers on the network.

Our response

I can confirm that Ordnance Survey does hold some of the information you have requested however, from our preliminary assessment, it is clear we will not be able to fully answer your request.

First, internet activity logs are only held for a period of approximately two months; this time period can vary slightly as it is dependent on the amount of disc space used with the oldest logs deleted as the disc space becomes full, so where there is high activity, the length of data retained is reduced. Therefore, Ordnance Survey does not hold the information you have requested for the past 12 months.

In relation to the two-month period for which we do hold relevant internet activity logs, the time spent dealing with your request will exceed a period of 18 hours. We are therefore entitled to refuse to comply with the request pursuant to section 12(1) of the FOIA (where the authority estimates that the cost of complying with the request would exceed the appropriate limit, which for Ordnance Survey is 18 hours).

To provide details of the 500 most accessed websites, the URLs and number of times each website has been accessed would involve producing individual user reports for all internet access for each member of staff. It would then be necessary to manually calculate the most accessed sites for each of the users and then aggregate these results to achieve the outcome required. As such, we estimate that it will take us in excess of the applicable time limit to locate, retrieve and extract the information in reference to your request.

However, under our duty to provide information and assistance in accordance with section 16 of the FOIA, we can provide the following information which may assist you in this matter. Please find top URLs report (PDF), which provides information on the top 20 websites for the past two months. Please note although the report states it is run from December 2016 to December 2017, Ordnance Survey only hold records for the past two months due to our storage capacity, as detailed above.
