One of my clients website is getting massive traffic from China most of which are bots. These bots are hitting the site nonstop causing the VM to use very high cpu and memory. As a result it is costing my client my as the site is hosted on cloud.
I have Blocked most of the IPs. I even blocked the whole country but that does not seem to help. Still the site is getting massive amount of hits per minute.
These bots are hitting one specific URL which had a Email form. I removed the email form. Changed the URL and even redirected the old url to a different site.
But none of these seem to have any effect of the CPU and RAM usage. Any help is appreciated.
