&gt;Layer 7 (“400 Bad Request”) attacks toward our public-facing websites<p>I really wonder what that is supposed to mean, Linode has mentioned it multiple times but not elaborated on what sort of an attack this is.<p>I personally haven&#x27;t ever head of a &quot;400 bad request&quot;-attack.<p>Edit: Yeah, I know what Layer 7 floods are :), but I&#x27;m pretty sure &quot;400 bad request&quot; floods are something Linode came up with, so that could use some elaboration by them.
