If a central server can be DDoSed, it doesn't feel like a "secure" service.

If everything's routed through a centralized hub, the hub could serve as a way point for attacking maliciously weakened end-to-end encryption via MitM interception, and collector of identifiers for metadata like device phone numbers.

I vouched for your comment even though I’m not sure if it was killed by downvotes or because your account is new. I think you have a reasonable comment; however, there’s a difference between security and reliability: end-to-end encrypted messages can be routed through a central location and still be “secure” in the face of a DDoS (but not able to function), and a federated service can be hopelessly insecure but still resilient to attacks like these. Telegram by default is not all that secure and centralized, and with their encrypted chats is hopefully at least secure (though I’m not sure if it is with regards to metadata).

They likely mounted attacks against Youtube when Guo Wengui was doing high profile live-streaming in 2017.

It wan right before he was scheduled to start, he lives in NYC.

What a weird title.

Telegram says this is mostly affecting the Americas https://twitter.com/telegram/status/1138768124914929664

The article itself says "IP addresses coming mostly from China" which would accurately describe most botnets.
