      I mean, that's really the only way. A DDOS is about exhausting resources so the best plan of action is to have more resources than your opponent can drain or proxy your stuff through someone who has the resources

      We had to rent 60 Euro per month server half a Europe away instead of 5 Euro per month server in Eastern Europe because it was the closest and cheapest server with protection against kind of ddos attacks that we were experiencing.

      ​​@@firebadnofire9768 Or obfuscate the public-facing IP so it's harder for potential attackers to even find the info they need to DDOS it.
      Also, by routing traffic through all their datacenters, even if an attacker manages to DDOS the fake IP, their botnet would be connecting to a bunch of different Steam servers rather than one single server, spreading out the attack and making it less effective

    You can also tell if you're looking at an SDR fake IP by checking if it starts with 169.254... as that's a reserved range of IPs that have no meaning on the open internet. They're similar to the 192.168... IPs used for LANs.

    • @Aarmastah
      @Aarmastah  4 วันที่ผ่านมา +22

      yeah it would've made more sense for me to have broken it out further, that way more of the "hops" increasing latency could have been seen whilst i was talking about them. absolutely valid criticism

    • @Flourish38
      @Flourish38 4 วันที่ผ่านมา +2

      ...So, it may be true that your packets are being sent to governments/universities (I assume you mean for tracking purposes?), but that doesn't mean that your traffic is being slowed down, or even that there are extra hops. Those are most likely to be side branches, as in additional destinations that your packet is being sent to for logging. The only benefit of adding an extra hop would be to perform a man-in-the-middle attack, but since almost all internet traffic is encrypted, it's very hard to do anything with it. ISPs work VERY hard to minimize the numbers of hops necessary, because the computers involved in a "hop" aren't cheap!!

  • @QualityDoggo
    @QualityDoggo 4 วันที่ผ่านมา +10

    Even if the route is not actually lower latency, the improved reliability easily makes up for it. TF2's interp system is surprisingly capable despite its flaws so a consistent connection with low jitter can be better than one where minimum latency is lower but jitter is high -- which is a common issue seen with "interference" from DoS traffic

  • @Capiosus
    @Capiosus 4 วันที่ผ่านมา +24

  • @IgorMAssis
    @IgorMAssis 4 วันที่ผ่านมา +9

    Fun fact: a DDoS attack would mostly focus on volumetry and try to saturate the metro region's transit capacity of Valve's edge connections, which would hinder player connectivity and make it unplayable. The actual servers and application nodes IPs are actually irrelevant when under a volumetric attack since everything would go down either way. What they're really trying to achieve with SDR is to seamlessly re-route user connections through different metro regions and to avoid dealing with endless firewall rules for each cluster as soon as they're being brought up or down from service. Hope that helps. Cheers.

    • @richardmillhousenixon
      @richardmillhousenixon 12 ชั่วโมงที่ผ่านมา

      By doing it the way they do, they ensure that even if an attacker manages to saturate one datacenter, your game can just switch over to the next closest data center as it's entry into the SDR network. You might experience a single lag spike while the transfer occured, but then it would be smooth sailing. An attacker simply wouldn't have enough resources to saturate more than a couple of datacenters, and Steam has several hundred.

    Valve has implemented this across their games including cs. The problem (although small) is that you don't get to choose which location it connects to. I've had moments where I was rerouted through Sweden for a server in Austria when I lived in Greece. The software especially glitches if for some reason you have high ping across all their servers (which happens a lot to me when I send lots of traffic to another server due to my low upload link). If valve would allow the user to select which servers to connect to, this feature would really be perfect.

  • @richardmillhousenixon

    As long as the server you're connecting to isn't closer geographically than the nearest Steam data center, I suspect SDR will almost always be at least a couple milliseconds faster than normal routing. The nearest Steam datacenter to where I live is less than an hour away by car, so there are very very few servers closer than that.

    I'm not sure if this is all accurate, I've joined servers where there's been weird lag and hitching and this is a semi-regular occurrence. Usually when this happens you hear a constant "soft fabric rustling" sound, this usually persists until the server restarts or empties out.

    It's a pity that Valve doesn't allow you to import your PGP keys to create a secure Internet connection with end-to-end encryption in Casual.
    At least Valve servers work with low ping, with the exception of MVM servers which like to lag. Sometimes when searching for community servers, there are servers with a ping of 60 to 33 ms. But once you connect to them, the ping becomes from 100 to 200 ms. I don't understand why this happens.
