DDOS attack

[AmonSul]

No, not for sure. But Swedish national TV broadcaster SVT streamed the current ongoing live event "Den stora älgvandringen" (the great moose migration) flawlessly during the Solar Flares to the internet. You can see some aurora borealis in live stream around 0:29 am today. For them it did not seemed to be a huge problem. SVT also use Arelion/Twelve99 as ISP btw, the same company that also SE uses for its EU servers.

As far as I know there is only one company in the world that is known to be immune to DDOS attack ... and it is Amazon. First, because Amazon is in the business of selling server so they naturally they always have a large reserve capacity. Secondly, and probably more importantly, they did the math and see that they stand to lose hundred of millions for each minutes the website is down, or even billions if it's during holiday season. I think in the past Amazon came under concentrate attack for a straight 3 days, then the attackers gave up because Amazon's servers just shrug it off. I have never heard similar thing from any other tech companies. The joke is you can't DDOS Amazon, because the massive amount of business they process at any given moment means they're already ALWAYS DDOSed by their actual customers.

But in case if anyone wondering why there is no business incentive to preemptively stop DDOS attack ... just looks at amazon to see how big such incentive needs to be.

yeah, in this one instance I would agree with the thought that some have here that SE is a "small indie company" in comparison. Amazon = $514 billion annually and SE...$2.49 billion... Amazon makes it money doing many sales online and SE doesnt, not many companies need that kind of "protection" against these kind of attacks. though, does Amazon have a real defense, or are they servers just much more robust because of the volume they need to handle on a normal basis?

That's exactly it, as other have said there is no "real" defense against DDOS beside outcapacity the attacker, Amazon's infrastructure is just "innate" in that regard. Basically they make sure they always have the capacity for holiday shopping (Prime day, Black Friday .etc.) when the traffic will increase many fold ... So to Amazon, a DDOS attack is no difference than the increase traffic spike they would see on a holiday, and they ALWAYS have more than enough capacity for it. Whenever an attack happens, Amazon's serve just look at it and thought "oh, is it Christmas today?" and scale up. Because of their ceiling is so high that I doubt any attacker would be able to exceed it.

I've heard that DDoS attacks can be costly for the attacker as well, so it's not really sustainable for a long period I think. I think also the longer the attack goes the more Intrusion Protection Systems (IPS) start to kick in...I found it very interesting but I plan to research it further because my brain isn't wrinkly enough for this.

So I wonder if it's more of a 'weather it out' kinda thing until the body guard kicks in.

My smooth brain translated DDoS to this following analogy

Imagine you're at a restaurant, making an order....suddenly an influx of hundreds of customers come in, they start to occupy the space and begin to engage with the staff be it by complaining or placing an absurd amount of orders. The staff is overwhelmed by this chaotic situation and you (the legit user) is not getting proper service. The manager (network admin) then calls the police (IPS) starts to restore order (mitigate the attack) by dealing with these troublemakers (malicious traffic)

I guess an upside of all this is a stress test for SE to hopefully prepare for DT. Here's to hoping for a smooth release...

For ddos attacks the prices differ massively, and prices arent linear. The heavier the attack, the faster the price goes up. And especialy when they become very heavy, its exponential. The price betweeen the strongest attack and one at half of that is a diffirence of like 500x here. Maintaining large botnets is very expensive.

This is why IPS systems are problematic for ddos attacks long term. Initialy the ddos is cheaper than the defense, but once they scale up, pricing here is quite linear. As long as you can buy a server, you already require a ddos to be significantly stronger to compensate.

Also, if its detected which sources are known to be part, they can be blocked well ahead of the target. It only needs to pass through 1 of the datacenters that are part of a global system to avoid big ddos attacks, and suddenly your attack becomes crippled. And yes, large datacenters do these things because they otherwise would also risk hardware damage when a target is near one of their DCs.

And again. Entire Group kicked out of a Trial with a 400 player login queue after. How many Days is this going to last? I hope they get this sorted before Dawntrail otherwise this is going to be a disaster.

[RulerKelso]

chaos - omega, booted out of game right now (error 900002), with over 700 queue, definitely DDOS-ed again

[PineconeKing]

Booted out from Ragnarok (Chaos) with a 90002 as well!

[StriderShinryu]

Coeurl on Crystal. Just got the boot with no ability to reconnect due to the usual errors. Looks like NA isn't out of the cross hairs this time.
