&gt; It&#x27;s not in anything that&#x27;s been leaked<p>Yes, it has been, though the exact nature of that &quot;data&quot; depends on your interpretation, and &quot;everyone&quot; is obviously only and approximate value. The NSA has even admitted to collecting most telephone records under the &quot;phone metadata program&quot;.<p>They also keep a sliding-window capture of data that includes a &quot;full take&quot; of the backbone in some areas. This was still being deployed at the time the leaked documents were written, so the coverage is variable, but we can assume it&#x27;s only increased. Note that this is covered by one of the NSA&#x27;s &quot;creative reinterpretations&quot;; they pretend that the data isn&#x27;t &quot;captured&quot; until someone actually looks the data up in XKEYSCORE. This is patently absurd.
