Sources

This Silk site uses only data retrieved from the official Transparency Reports of each companies. Below you find the links to the originals. All the data has been carefully copied and double-checked, but should you find any inaccuracy, please contact us and we'll be glad to look it over.



Methodological Notes

Since every country has different standards for publishing the information, we had to normalize it to make it comparable. Here are some transformations we did on the original data. 

  • Twitter uses the value "< 10" for countries that submitted less than ten requests. Other companied on the other hand published the exact number. To carry out calculations and comparisons with the Twitter data, all " < 10" have been converted to the middle value of 5.5.
  • Apart from the data included here, Dropbox has received 90 requests from non-US countries, to which, for legal reasons, Dropbox hasn't disclosed data. Dropbox didn't publish the names of the countries that have filed these requests, and therefore aren't included in this Silk for now.
  • Most companies publish reports on a 6 month basis. There are some exceptions of companies that in some cases have published a yearly report. In these cases, the data on the requests has been divided by two, and each half assigned to six months of the year, so that it would be aligned with the other Transparency Reports. This operation has been done in the following cases:
    • AT&T (2013)
    • Cloudfare (2013)
    • CREDO (2013)
    • Dropbox (2012 and 2013)
    • Sonic.net (2011 and 2012)
    • Microsoft (2012)
    • Tumblr (2013)
    • Verizon (2013)
  • Verizon doesn't publish information on the number of requests it complies with, therefore this data is missing also from this Silk.
  • AT&T doesn't publish information on the number of requests it complies with in a clear way: it combines requests that don't produce data with requests that lead to the disclosure of "partial data". This is ambiguous and differs from the clearer distinctions offered in the reports of all other companies, where the disclosure of "partial data" is separated from "no data disclosure". For this reason information on AT&T compliance rate is left empty.
  • A note on the United States, NSL and FISA. The data in this Silk contains only requests that the USA have submitted through ordinary legal processes, like Court Orders, Subpoenas, Search Warrants, etc. In January 2014, the US Department of Justice announced that it is now possible for companies to release information on the amount of National Security Letters and FISA received, in ranges . While these broad ranges might give some insights, in practice it is impossible to carry out any proper data analysis. For this reason, and because not every company has yet updated their Transparency Reports with this information, we chose to exclude this type of data from this database. At least for now.
