Comment on Why Signal’s post-quantum makeover is an amazing engineering achievement

  It's not completely out yet. That was likely AWS being down.

  Also, the new quantum protected message encryption headers are about 2kb. If that's causing issues with your internet, you may want to consider looking at new internet.

    2kb? While it may not sound like much, that’s at least three packets worth of data (depending on MTU). If you think about it in terms of how TCP sends packets and needs ACKs, there’s actually a lot of round trip data processing going on for just that one part.

      TCP will generally send up to 10 packets immediately without waiting for the ACKs (depending on the configured window size).

      Generally any messages or websites under 14kb will be transmitted in a single round-trip assuming no packets are dropped.

    The average for a person sending / receiving a message is about 35 / day. That’s 70kb / person.

    Signal has aprx. 100 million users.

    Which means this adds about 7 terabytes daily.

    Just doing the math on it, there’s no point to this message 😁

    Sorry, yeah, that’s what I was referring to.

    My internet connection is 500/500 Mbps, and I can’t change it. 😄👍

      Should have been pretty obvious to anyone reading any tech news whatsoever today, especially in the context of where you responded. No apology from you should have been necessary!

        You would think 😅 The sorry was sightly sarcastic, but shhh, nobody need know
