China is doing a mass arrestment*1 of 100+ human right lawyers last weekend, in the same times as DDoS start and end, and there's a news from China's official news agent indicate that Telegram is the main secret contacting tool that human right lawyers used.
Some people think it's China who attack Telegram, to avoid the lawyers to warning each other for the arrestment.
We know from this year's GitHub attack that (a) China is willing to DDoS foreign internet services, and (b) China is able to enlist foreign traffic to carry out the actual attack.
So it wouldn't be surprising if China DDoSed Telegram and made it look like the attack came from South Korea.
