They Watched Everyone: How XKeyscore Swallowed the Internet

Twenty terabytes of data vanished every single day from collection points that could only hold a fraction of what they took in, and XKeyscore was the system swallowing it all. Documents disclosed in July 2013 show it ingested “full-take” internet traffic across hundreds of sites in allied countries - so who exactly was being watched, and how could such scale remain secret?
In this episode, we lay out the documented record of XKeyscore’s architecture, data flows, and the evidence that revealed its global reach. We trace how ordinary internet packets routed through foreign servers became part of a system that kept metadata for up to 30 days and content for only a few days, and ask what that reality meant for citizens and partners.
Person: Edward Snowden
Date: July 2013
Event: First confirmed public account of XKeyscore
Servers: more than 700 servers
Sites: roughly 150 collection sites
- The system collected "full-take" data, ingesting every packet passing a collection point before filtering.
- Metadata retention was up to 30 days while content was retained for 3 to 5 days, with some sites holding content for only 24 hours.
- By 2008 XKeyscore ran on over 700 servers distributed across about 150 sites including military bases, embassies, and allied facilities.
- Data sources included Special Collection Service, FORNSAT, Special Collection Operations with telecoms, spy planes, drones, TAO hacking, and FISA-authorized domestic collection.
- Edward Snowden, a 30-year-old NSA contractor, provided the documents that made XKeyscore's capabilities publicly known.
