holy hell
[QUOTE=Squad;40062188]Not that much? So most companies charge an overage. I looked up one random company and they charge $0.15 for each GB overage. 300 Gigabits is around 37 or something gigabytes. And that is every second... There are 86400 seconds in a day. So if they DDoS for an entire day, that is $483,840. That is per day... Can you imagine losing half a million dollars a day for something you don't control?[/QUOTE] Amazon charges $0.120 per outgoing GB, luckily incoming is free. Also, don't use AWS to Ddos (Cloudflare said something about it), not only is it against their TOS, but it will cost a fuckton.
I find it kinda worrying how the Internet could go down so easily

[QUOTE=RoflKawpter;40059478]I..... What?[/QUOTE] Because why the fuck not.
My dedicated server once got D'dosed once (5gb/s) for 5 hours straight and if I hadn't of had the unlimited data plan I have payed $1.50 per gigabyte of my limit was 1000gbs. The math on that hurts my brain and I probably would have committed suicide if that would have happened. :)
90,000 Gigabytes for the five hour total. Let's subtract your maximum limit of 1,000 Gb, and that would make it 89,000 left over. So you would of had to pay $594 to cover the DDoS. EDIT: I did that wrong the total cost would be $133,500. 1.50 per GB so 1.50 * 89,000 = 133500
so maybe that's the reason why my ISP is so slow now well fuck you and kill yourself the one who caused DDoS attack
This wouldnt have anything to do with the "Error 103 (net::ERR_CONNECTION_ABORTED): Unknown error" I've been getting on my wireless connections then?
Oh this might explain some things then
[QUOTE=Aetna;40059472] When you are the target of a DDoS attack, you don’t lose your connection to the internet because your hardware (router/modem) fails. You lose connection because you are using the maximum amount of bandwidth your ISP allocates for you. If your download speed is 25 Mbps and your attacker is targeting you with 100 Mbps worth of traffic, you are not actually receiving all of that traffic, because your bandwidth is throttled to 25 Mbps. This is why DDoS attacks do not cause physical damage to residential hardware. If an attacker tells you that he will, “fry your router”, he’s either just saying that for the effect, or has no idea what he’s talking about. [/QUOTE] Actually, this isn't the case either. The problem is that routers have a connection tracking table of limited size. This table is used to track connections between machines on the local network to the WAN and vice versa. On home hardware routers, the table is usually 1000 entries, but custom firmware like DD-WRT can increase the table size (whether or not the router can actually handle this increased size is unknown.) When you get DDoS'd, the connection tracking table is completely saturated and no new connections can be created going either way, which is why the internet appears to not work. If you could keep the connection tracking table from being occupied by bad entries (from DDoS) then your internet connection would still be usable, just really slow. But most home routers are dumb and don't have features to stop this and are overwhelmed. And the reason they stop working after the attack is over is because they're unable to clear the conntrack table and need to be rebooted. But sometimes they can overheat (like MIPS pointed out) and won't work until they cool down again. You can look at the connection table for your local computer under Linux with the "iptstate" bash utility, which will list all incoming and outgoing connections.
