In theory, to the browser, and that will show an error message. But during a HTTP flood the attacker simply sends requests as fast as it can, without looking at the result or errors. Basically like when you're holding down F5 in your browser (please don't try, you might get your IP banned)
In a ddos situation, the communication between server and browser is unreliable at best. What I meant was a signal from your servers/load balancer to the ISP, which can then react by switching to more restrictive filtering for your IPs. It would be a small part of the solution when a perfect solution doesn't exist anyway.

Such a mechanism doesn't exist, and bad ISPs will ignore it anyway. There exists a mechanism called "abuse reporting", which sends an email to the ISP, so they can investigate, which will never happen.

I can just drop packets at our server's NIC, so they consume as little CPU time as possible. If that's not enough, I can talk to our ISP and get certain IPs/IP ranges/ASNs nullrouted. For very big attacks, see what @Solaris17 wrote.

Hmm... CAPTCHA implementation after a certain number of requests / minute?
Yeah that's one option, and usually ends up with "more requests" (so our requests/minute counting overwhelms the CPU), or more IPs (so they can run at "max requests per minute minus one").

DDOS is basically a cat and mouse game, but I see no reason to invest hours of my time, when they take us down for minutes only

hey speak HTTP 2.0, so not some printers. Another attack had randomly crafted query strings and HTTP referers
I have proved myself too ignorant to be the attacker.

Which is what i want you to think.

Just got hit by a DDOS attack, banned around 200 IPs and things seem better now
Someone seems pissed off. Why do I say that?...

...this. This says directed attack. Likely someone who got banned or given time-out having a tantrum. All too common.

I enjoy our debates! We can easily disagree with each other, it never gets personal and we still continue to respect each other. :toast:

But this meanders from topic, so I digress..

Not reporting an issue, just wanted to say I started using this website recently on my phone and wow it an awesome and fluid experience. I was not expecting this is all.

These forums have always impressed me, with how everything is laid out, how double posts auto merge, the overall look of everything. It's wild how just viewing this site on Firefox on my phone is just as smooth looking and functional.

Very well designed. 10/10 w1zzard is actually a wizard. :lovetpu:
