I basically want to know if DDOSing using a single pc with 20 threads on HOIC or LOIC be different based on sites? There is a project website I made which goes down in a minute after the DDOS starts. (www.aroosani.net) But there are some other medium-size ones that don't even slow down. So how do I know if a site can handle less or more bandwidth?

    It depends of how much server they have, how fast is there process, how much bandwith they have ... – Xavier59 Sep 21 '16 at 17:52
  • @Xavier59 I think he understands that. The question to me, seems to be, how to tell the bandwidth of a given web-host? I'd assume the service providers would list this, but I can't seem to find hard numbers on any providers website... a lot of them list their bandwidth as "unlimited" – INV3NT3D Sep 21 '16 at 17:59

    Nitpicking: When it is an attack from a single PC, then it is just a DOS attack. The first D in DDOS stands for "distributed". – Philipp Sep 21 '16 at 18:00
  • Define "medium-sized ones"? You might be able to define the difference yourself. Also, some sites have DDoS protection that drops attacks packets (and that does not require a certain 'size'). There are many factors in play that you need to account for, not just bandwidth. – schroeder Sep 21 '16 at 21:03

Have you checked whether this is actually bandwidth related? Is the bandwidth actually max'd out? Or is it the web site itself that cannot keep up with the volume of incoming requests?

Generally, the last is more likely and would often be why you see the issue on one site and not another. The number of requests a site can handle is heavily dependent on the server technology being used (both the web server and any scripting such as PHP or Node.JS), page sizes and complexity, memory utilisation and availability and so on.

You need to provide some stats from the sites if you need specific help. You also need to share what technology you are using. Both software and hardware.

As a final note, the use of a CDN can massively help protect against DDOS. Services such as Cloudflare have a number of features that will both protect against and mitigate DDOS attacks on your site.


Usually, apache webservers hosted on low-resources like VPS are more vulnerable to DOS attacks due to his process-based system and his slow http "vulnerability".
