Im from Turkey and I don't recall any particular move let alone this big. It was probably "deep web fad" or something about Tor.

Also, this peak also happens at other countries, alth. they vary by size. https://metrics.torproject.org/users.html?graph=userstats-re... This is singapore, I have looked at others(uk etc.) and they are same too.

That was the Sefnit botnet which started to use the Tor network heavily in mid-August 2013.
