Lol. M9 is the peering facility in Moscow, a former telephone exchange, which housed tons of KGB monitoring equipment as well which transitioned to the FSB after the iron curtain fell. At one point it was said that 70% of Russia's internet ran through that building. M9 is the original Moscow Internet exchange, MSK-IX , IX being industry terminology for Internet exchange (similar to PAIX for Palo Alto Internet Exchange, and Equinix the data center provider) but is also a clever use of IX as the roman numeral 9 hence M9/MSK-IX. MSK-IX the company also has Internet exchanges in another half doezen or so Russian cities.
20T is a lot of data depending on what it is (text records on activists/spies/war targets?) and M9 is not a small ISP.
