Yes, in certain cases a VPS server can be affected by other VPS on the same physical server. Some of the ways that this might occur include:
1. Overutilization of shared resources: All VPS on a single physical server share the same resources, such as CPU, RAM, and storage. If one VPS is using a disproportionate amount of resources, it could slow the performance of the other VPS on the same physical machine.
1. “Noisy neighbours”: This is a term used to describe a situation where one or more VPS are generating significant network traffic, causing lag or slowdowns for the other VPS on the same physical server.
1. Security vulnerabilities: If a user on another VPS is able to exploit a security vulnerability in the hypervisor (the software that creates and manages the VPS), they could potentially gain access to your VPS or disrupt its operations.
1. Hardware failure: If the physical server experiences a hardware failure, all of the VPS hosted on it will be affected.
However, good hosting providers often have safeguards in place such as network and resource management tools to distribute resources fairly among all users and prevent one user from monopolizing the resources. They also regularly maintain and update their physical servers and hypervisors to limit the chance of failures and vulnerabilities.
