The Washington Post: NSA "writes" 100% of all calls from an unnamed country

One of the “fly” slides for NSA employees. The
details of an organization such as the NSA, gradually, with the filing of Edward Snowden, are overgrown with more and more details, often almost fantastic.
For example, it was previously reported that in the United States there is a system that works in the interests of public services, which records phone numbers, call time, and sort of like a phone call. But no one said that there is a system that records telephone conversations themselves, and the system stores audio recordings for 30 days. This system does not work for recording calls within the United States, but in some unnamed country (which one, the journalists of the publication failed to find out). All this was put into operation in 2009, and the system reached full capacity in 2011.
The telephone interception and recording system itself has received the promising name MYSTIC. This is an abbreviation, but an abbreviation with meaning - after all, only the paranoid and some information security experts believed in state surveillance systems that record citizens' phone calls. And now it turns out that the "mystical", non-existent system is reality.
At the same time, not only the NSA has access to the MYSTIC database, but also other government services and organizations. If someone begins to suspect a telephone number of “cooperation with foreign intelligence”, or other bad things, in the database by the phone number you can find a record of the conversation of the number owner with his telephone interlocutors. Let me remind you, records are stored for 30 days, after which, when new data arrives, old files are overwritten. According to The Washington Post, we are talking about millions of records every month.
In addition to this unnamed country, the NSA planned to introduce a similar system into the telephone networks of some other countries. But which countries are in mind - not yet reported.
