Black Friday is pretty much a tat sale now.
If an organised and sustained effort to browse heavily some website took place, would it be enough to cause increased website costs for the company?
The big sites planning their year on selling masses of junk on one weekend no doubt expect their systems to scale up accordingly, and they plan for that cost.
How much browsing, by how many more people browsing and not buying, would be needed to cause them significant costs?
Possible?
So many companies don’t value their customers, their data or value.
It is time to change that, but how?
The concept you are talking about is a called a Denial of Service (DOS) attack. Typcially that is down with malware, there is another type that uses bots that is called a Distributed Denial of Service (DDOS) attack. In a DOS attack the malware overwhelms the capabilities of a website, email server, ftp server etc to the point where it fails.
If the number of people browsing the site do not overwhelm the site it won’t cost the company shit. Any CDN/web hosting company worth a damn will have the capacity to handle the black Friday weekend surge.
